Question

what is a repulsion of 2 bar magnets​

Answer 1

Answer:

The force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current. It is repulsive if the currents are in opposite directions...

Answer 2

1. The force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current.
2. For example, the force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
3. Two circular current loops, located one above the other and with their planes parallel, will attract if the currents are in the same directions and will repel if the currents are in opposite directions.
