Question

Which of the following is NOT a method for making a magnet out of a metal which has the ability to be magnetized a) by striking the metal b) by exposing the metal to another magnet c) by super radiating the metal d) by running electricity through a coil wrapped around the iron​

Answer 1

Metals can be magnetized through striking, exposure to another magnet, or running electricity through a coil around the metal. However, 'super radiating' is not a valid method for magnetizing metal.

Step-by-step explanation:

The question is asking about various methods of magnetizing metal. Most metals can be magnetized through methods such as: a) striking the metal in a single direction which can align the metal's atomic magnetic fields, b) exposing the metal to another magnet, allowing its magnetic field to change the alignment of the metal's atomic magnetic fields, or d) running electricity through a coil wrapped around the metal, again, changing the alignment of the metal's atomic magnetic fields, creating a magnet.

However, method c) super radiating the metal is NOT a valid method for magnetizing metal. The term 'super radiating' does not refer to a recognized physical process involved in magnetization.
