Consider a metallic pipe with an inner radius of 1cm. If a cylindrical bar magnet of radius 0.8 cm is dropped through the pipe, it takes more time to come down than it takes for a similar unmagnetised cylindrical iron bar dropped through the metallic pipe. Explain.

Question

(a) Due to magnetic flex linked with the pipe
(b) Due to induced current developed in th pipe
(c) Due to the eddy currents developed in the pipe
(d) none of the above
