Question

If a current flows in the Satellite Tether shown in Figure 23.12, use Faraday’s law, Lenz’s law, and RHR-1to show that there is a magnetic force on the tether in the direction opposite to its velocity.

Short answer

The direction of force is opposite to the direction of motion.

Step-by-step solution

Define Electromagnetic Induction

Due to the motion of a conductor in an external magnetic field, an emf is induced in the conductor such that the emf will try to oppose the motion of the conductor. This phenomenon is called Electromagnetic Induction.

Explanation

In this case, the direction of the current is upward, while the direction of the magnetic field is into the plane. With the help of a correct application RHR-1, it can be found that the direction of the force will be to the left, that is, opposite the velocity.

Therefore, applying RHR-1 we directly can find the direction of the force to be opposite that of the velocity.
