How is an electro magnet different from a bar magnet?

Answer 1

An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

Answer 2

An electromagnet is a magnet controlled by the electrons shifting inside it, so when an electrical current goes through it, the electrons align and it is magnetized A bar magnet is just a piece of metal that has been magnetized meaning the atoms inside are permanently fused in the aligned. An example of a Electromagnet would be a crane at a junkyard, who has a electromagnetic disc on the end of the crane to pick up large pieces of metal. An example of a bar magnet is refrigerator magnet.

Answer 3

An electromagnet is created by passing an electric current through a coil of wire, generating a magnetic field. A bar magnet is a permanent magnet that retains its magnetic properties without the need for an external power source. Additionally, the strength of an electromagnet can be controlled by adjusting the amount of current flowing through the coil, while the strength of a bar magnet is fixed.

Answer 4

So long the current flows through the magnetism would exist. If current is off then magnetism disappears. So temporary magnet

But bar magnet is a permanent one.
