Is electromagnetic induction possible in DC?

Alternatively, an electromagnet powered by a fixed DC voltage can be made to rotate inside a fixed coil, such as in large power generators producing in both cases an alternating current.

How does a DC electromagnet work?

An electromagnet is simply a coil of wire. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.

What happens if DC is applied to transformer?

When a DC voltage is applied to the primary winding of a transformer, due to low resistance, the winding acts as a short circuit across the terminals of the DC source that lead to the flow of heavy current through the winding resulting in overheating of the winding.

Why does DC current not produce magnetic flux?

DC current does product magnetic flux. In fact any charge motion will produce magnetic flux. But with DC, since the current is constant, the flux also remains constant. This is why it cannot be used in transformer, since a constant flux associated with secondary winding, won’t create any emf in the secondary.

Does current affect the magnetic field of a conductor?

Yes, it does. Direct current flowing through a conductor creates static magnetic fields, which remain constant with respect to time. , In electrical power business for 30 years. As long as there is current flowing there will be magnetic field. At constant current the magnetic field of the current is constant.

Can a DC motor produce magnetic field?

Answer Wiki. Yes D.C. Electricity produce “static” magnetic field. If D.C. Electricity will not produce magnetic field then no concept of D.C. motor or generator.

What is the source of magnetic flux through the coil?

This magnetic field passes through the loop and is the source of magnetic flux through the coil. As the loop slides by position 1, the flux through the loop is INCREASING and it is Pointing OUT OF THE PAGE. As the loop slides by position 2 the flux through the loop is DECREASING and it is pointing INTO THE PAGE.
