Magnetic needles are usually artificial magnetic alloys are used to make artificial magnet . How do make strong magnet using alloys?
Making strong magnets from alloys involves combining different metals with specific magnetic properties. The most common strong magnets are made from alloys of iron, cobalt, and nickel. The process begins by melting the metals together and then cooling them in a very precise way. This is followed by hardening the alloy through a process called annealing. Finally, the alloy is cut and shaped into the desired form. The result is a very strong magnet that can be used in a variety of applications.
