Question

can we make a permanent magnet more stronger by electricity​

Answer 1

Answer:

By reducing the electrical resistance, much higher amounts of electrical current can be put through the magnets, thereby generating a much stronger magnetic force. ... The strongest permanent magnets are made from an iron-neodymium-boron (Fe-Nd-B) alloy.

Answer 2

Answer:

By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak.
