Question

State Right-hand rule with a labeled diagram.

Answer 1

Hint: In this question, we can use the concept that the direction of the force is indicated by the thumb, the direction of the magnetic field is indicated by the middle finger and the middle finger indicates the direction of the current. The right-hand rule gives us the direction of the current flow.

Complete step by step solution:

The above figure shows the right-hand rule which indicated the three fingers thumb, forefinger, and the second finger. The thumb denotes the direction of the force(motion), and the fore finger represents the magnetic field, and the second finger represents the direction of the current. It is used to determine the direction of the induced current in a conductor that is moving inside a magnetic field. If the axis is grasped in the right hand then the fingers curl in the direction of the positive rotation, and the thumb is oriented in a positive direction.
They give me the direction of current flows. Imagine that you have held a current-carrying straight conductor in your right hand in such a way that your thumb points in the direction of the current. Then turn your fingers around the conductor. The direction of the fingers in the direction of the magnetic lines of force produced by the current.
As the conductor connected to a circuit moves in a magnetic field. The right-hand rule indicates the direction of the magnetic field. It can use the concept of the FBI where F is the force, $B$ is the magnetic field, $I$ is the current.

Note:
To remember the right-hand rule, the first thing that is to remember the FBI
$F$ defined as the force of motion.
$B$ defined as the magnetic field.
$I$ defined as the induced current or the direction of the current.
Students often get confused between the right-hand rule and the left-hand rule. Remember the left-hand rule is used in the case of electric motors.
