Question

Decribe how will you magnetise a steel rod in earth magnetic field

Answer 1

Magnetism occurs when negative and positive particles in an object line up in a specific manner, causing an attraction or repulsion with nearby particles. As long as a metal has some iron in it, you can magnetize it using another magnetic metal or an electromagnet.[1] While you need a strong magnet to make another metal magnetic, the magnetism produce will probably not be very strong; it will be sufficient to pick up a paperclip or a screw. The strength of the magnet depends upon the iron content.
