Copper is a non-magnetic metal, meaning it is not attracted to magnets. However, when a magnet is moved through a copper coil, it creates an electric current which in turn generates a magnetic field, creating a repulsive force between the two.
When a magnet is moved through a copper coil, it creates a changing magnetic field. This changing magnetic field induces a current in the copper coil, which in turn creates its own magnetic field. This magnetic field interacts with the magnet's field, producing a repulsive force.
The strength of the repulsive force depends on several factors, including the strength of the magnet, the speed at which it moves through the copper coil, and the size and shape of the coil. The distance between the magnet and coil also plays a role in determining the strength of the force.
Yes, the repulsive force generated between copper and magnets can be harnessed to produce electricity. This principle is used in generators and motors, where the motion of magnets through copper coils creates electricity.
Some common applications include generators and motors, which use this repulsive force to produce electricity and power various machines and devices. This principle is also utilized in magnetic levitation trains and other transportation systems.
