How can we make magnetic?
We make magnets by exposing ferromagnetic metals like iron and nickel to magnetic fields. Moreover, when we heat these metals to a certain temperature, they get permanently magnetized. Besides, it’s also possible to temporarily magnetize them by using a variety of methods that you can try safely at home.
