The magnetic field interacts with metal to generate heat in the metal which causes forming process.(a) True(b) FalseThis question was addressed to me during an online interview.Query is from Electromagnetic Forming in section Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer»

The correct option is (B) False

Best EXPLANATION: In the electromagnetic forming process, eddy currents are induced in a conductive material that is placed near to the coil. Then it interacts with a magnetic field to cause mutual repulsion between the metal and the forming coil. This FORCE of repulsion is mainly responsible for inducing stresses in the metal BEYOND its yield strength which RESULTS in plastic deformation of metal.
