Highlights three methods of making magnet?

1. Electromagnetic induction: This method involves passing an electric current through a coil of wire to create a magnetic field. The coil can be wrapped around a magnetic material such as iron to induce magnetism in the material.

2. Rubbing: Rubbing a piece of iron or steel against a magnet can also create a magnet. This method is known as "rubbing" or "stroking" and involves aligning the magnetic domains in the material to create a magnetic field.

3. Heating and cooling: Heating a magnetic material to a high temperature and then allowing it to cool in the presence of a magnetic field can also create a magnet. This method is known as "annealing" and is commonly used to create permanent magnets.

1. Stroking: Rubbing a permanent magnet along a piece of ferromagnetic material (such as iron, nickel, or cobalt) in one direction over and over again will align the domains within the ferromagnetic material, causing it to become magnetized.
2. Electric current: Passing an electric current through a wire coiled around a ferromagnetic material will create a magnetic field, which will magnetize the ferromagnetic material.
3. Induction: Placing a ferromagnetic material in the presence of a strong magnetic field will cause the domains within the ferromagnetic material to align with the magnetic field, causing it to become magnetized.
