How do electric currents affect magnets poles? Magnetic poles always exist as north-south pairs. Like poles repel like and attract unlike. An electric current in a wire generates a magnetic field around the wire. The direction of the magnetic field (clockwise or counterclockwise) depends on the direction of the current.
How does electricity affect magnetism? Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow.
Can electric current produce magnetic effect? An electric current produces a magnetic field. This is possible when an electric charge is in motion. … When the atom spins and orbits the nucleus there is a production of the magnetic field. Also, the direction of the magnetic field is determined by the direction of spin and orbiting of the electric charge.
How does current affect magnetic field? Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. … If the current is doubled the force on the conductor will double. If the current is is reduced to a third of the initial value the force will also reduce to a third of its initial value.

What are the heating effect of electric current?
When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called heating effect of current.
Why are electrical outlets in pairs?
Most 120-volt electrical outlets come in pairs arranged vertically in what are known as duplex receptacles. … The most common reason for installing one is to control a switched lamp on one of the outlet receptacles while leaving the other receptacle free for plugging in other appliances.
