Question

draw and explain construction of bar magnets by any one method​

Answer 1

Explanation:

They are made by surrounding certain materials with a coil of wire. When an electric current is passed through the coil, these materials exert a magnetic force. ... For a rectangular or cylindrical bar magnet, these poles would be at opposite ends

Answer 2

Construction of bar magnets:

• We are making a bar magnet have a certain that is spirally wounded around a tube.
• The tube is made out of a material that is not conducting for physically and insulating material while the material used in making the spiral is a wire that is made out of certain conducting material like Copper or any other material that can conduct electricity better.
• Now when the current moves around the spiral wound that is present on the tube.
• There are two poles generated in the corners or end of the tubes and changing poles of the voltage that is applied for the direction of movement of current changes the poles will also change.
