Given information
Given:
copper or aluminum is used as material for rotating wheel,
To determine, will eddy current brake work on such wheels or should the material have to be ferromagnetic.
Step-by-step explanation
Step 1.
According to the right-hand rule, moving charges in a magnetic field will experience a magnetic force, making them move and creating an eddy current. These induced currents will experience a force opposing the original motion of the piece of metal and the eddy current brake will begin to slow the wheel.
