The lines of magnetic flux are in the shape of concentric circles and perpendicular on the conductor (at right angle of 90o) as shown in fig. The direction of current and magnetic field can be found by the following rules i.e. right hand gripping rule, the end rule, corkscrew rule, Fleming’s left and right hand rules etc. If we consider current flow as the movement of positive charge carriers (conventional current) in the above
image, we notice that the conventional current is moving up the page.

• Note how the first segment of the thumb in Lateral Turncoat shown above left does not touch either chopsticks at all.

• Pete McCall, the education director for EOS Fitness gyms, also recommended a dead hang — the starting position of a pull-up.
• Next, align your thumb in the direction of the
  induced magnetic field and curl your fingers.

Since a conventional current is composed
of positive charges, then the same current-carrying wire can also be described as having a current with negative
charge carriers moving down the page. Although these currents are moving in opposite directions, a single
magnetic force is observed acting on the wire. Therefore, the force occurs in the same direction whether we
consider the flow of positive or negative charge carriers in the above image. Applying the right hand rule to
the direction of the conventional current indicates the direction of the magnetic force to be pointed right.

Righthand Rule vs. Standard Grip

In both situations, the right hand grip rule is applied to two applications of Ampere’s circuital law, which relates
the integrated magnetic field around a closed loop to the electric current passing through the plane of the closed loop. In the first wire, the flow of positive charges up the page
indicates that negative charges are flowing down the page. Using the right hand rule tells us that the magnetic
force will point in the right direction. In the second wire, the negative charges are flowing up the page, which
means the positive charges are flowing down the page.

• Then, point your index
  finger in the direction of vector a and your middle finger in the direction of vector b.
• The hilarious chopstick video from the Corridor channel on YouTube shows the following chopstick wrapper.
• There are two ways to do the right hand rule, and they take practice to conceptually understand, but this will make solving problems much quicker.
• Helices are either right- or left-handed, with curled fingers giving the direction of rotation and thumb giving the direction of advance along the z-axis.

A three-dimensional coordinate system in which the axes satisfy the right-hand rule is called a right-handed
coordinate system, while one that does not is called a left-handed
coordinate system. Similarly, When the observer sees at the facing end of the coil, if current flows in the anticlockwise direction, then the facing end of the coil behaves like a North Pole “N” and the second end behaves like the South Pole “S”. From the diagram it is clear that the moment arm r is just the magnitude of the component ┴ vector, in the perpendicular-to-the-force direction, of the position vector of the point of application of the force.

Now, the curled fingers show the direction of the magnetic field around the wire and how the compass would line-up if placed at that point. When an electric current passes through a solenoid, it creates a magnetic field. To use the right hand grip rule in
a solenoid problem, point your fingers in the direction of the conventional current and wrap your fingers as if they
were around the solenoid.

Experts said most people don’t need grip-specific exercises unless they are recovering from an injury or training for a sport like golf or tennis. They suggested limiting these to once a week unless otherwise recommended by a physical therapist. Here are a few exercises that experts recommend https://1investing.in/ to increase your hand strength; they can be incorporated into your existing workout routine or done separately. Here we show the last illustration from the wrapper next to a picture of the Righthand Rule grip. We have enlarged the three figures shown in the instruction for clarity.

1 Right Hand Rule

That being said, we should note that there is yet another alternative grip which looks not only like the illustration, but is virtually identical to it. That is the Flexed Middle variant (below left) of the Finger Pistol grip. You will see that for $F1$ your thumb points into the page (which is the direction for clockwise motion). Using this x and y, let’s use the right-hand rule to find the direction of z. Free-weight exercises — using barbells, dumbbells or kettlebells — are another opportunity to sneak in a hand workout by intentionally increasing your grip.

Right-hand rule

A student needs to understand the topic and the elements of it in order to learn it. The right-hand grip rule is also known as corkscrew-rule and it was named after the French physicist and mathematician Andre-Marie Ampere. It is used to show the rotation of a body or a magnetic field and represents the connection between the current and magnetic field around the wire. To understand how Lenz’s Law will affect this system, we need to first determine whether the initial magnetic field is
increasing or decreasing in strength. As the magnetic north pole gets closer to the loop, it causes the existing magnetic
field to increase.

Physics:Right-hand rule

Before we can analyze rigid bodies, we need to learn a little trick to help us with the cross product called the ‘right-hand rule’. We use the right-hand rule when we have two of the axes and need to find the direction of the third. The simplest way to strengthen your hands is by modifying exercises you already do.

Reputed physics tuition that offers JC Physics tuition classes will make it easy for you to learn physics. Once a tutor clears up the basic concept for the student, it will be easier for them to understand the complex topics thereafter. In the diagram above, the thumb aligns with the z axis, the index finger aligns with the x axis and the middle finger aligns with the y axis. It’s important for you to be able to envision how the axes are perpendicular.

There are a few variations of the right hand rule, which are explained in this section. Lenz’s law of electromagnetic induction is another topic that often seems counterintuitive, because it requires
understanding how magnetism and electric fields interact in various situations. To apply the right hand rule to cross products, align your fingers and thumb at right angles. Then, point your index
finger in the direction of vector a and your middle finger in the direction of vector b. Your right thumb will point
in the direction of the vector product, a x b (vector c). Since the threads of a screw are in circular shape, the same is the case for magnetic field lines (which are in circular form).

Positive and Negative Torques

This is illustrated in Figure A.14. Thus, you can often avoid using equation A.1 and instead use the right hand rule to determine the direction of the cross product and equation A.2 to find its magnitude. Helices are either right- or left-handed, with curled fingers giving the direction of rotation and thumb giving the direction of advance along the z-axis. For right-handed coordinates, the right thumb points along the z-axis in the positive direction and the curling motion of the fingers of the right hand represents a motion from the first or x-axis to the second or y-axis. Like many alternative grips, Righthand Rule is able to exert considerable power when closing salad tongs. But it does not derive power mainly from the tripod hold as Standard Grip does.

Thus, the induced magnetic field will have the
same direction as the original magnetic field. A helix is a curved line formed by a point rotating around a center while the center moves up or down the z-axis. Helices are either right or left handed with curled fingers giving the direction of rotation and thumb giving the direction of advance along the z-axis. For left-handed coordinates, the left thumb points along the z-axis in the positive direction and the curling motion of the fingers of the left hand represents a motion from the first or x-axis to the second or y-axis. When the magnetic flux through a closed loop conductor changes, it induces a current within the loop. The induced
current creates a secondary magnetic field that opposes the original change in flux that initiated the induced current.
