Question

Show work please A classic demonstration illustrating eddy currents is performed by dropping a permanent magnet inside a conducting cylinder. The magnet does not go into free fall. Instead it reaches terminal velocity and can take a few seconds to drop a length of about a meter. Suppose the mass of the magnet is 100 g and it has a constant, terminal velocity of 10 cm/s. The length of the pipe is 80 cm. What is the magnitude of the magnetic force on the magnet when it is falling at the terminal velocity? A) 0.80 N B) 0.49 N C) 0.98 N D) 0.69 N E) None of these is correct. Dielectrics are used in between capacitor plates to decrease the chance of dielectric breakdown. True or False

Explanation / Answer

When magnetic force & weight of the magnet gets balanced that magnet falls with terminal velocity.

Weight of the magnet = magnetic force

So,

Magnetic force = (100/1000)*9.8 =0.98N
