Select all the correct answers, which two statements are true? a moving magnetic field creates an electric field. a constant magnetic field creates an electric field, a constant electric field creates a magnetic field, a moving electric field creates a magnetic field. reset

A constant magnetic field creates an electric field.

Explanation:

Well, by definition, a magnetic field produces forces on moving charges. So if there’s just a magnetic field, and there’s a conductor with no charges already moving, there’s no reason for them to start to move, and plenty of reason (Ohm’s law) for them to stop.

Mind you, if you drag the conductor sideways through the field, the magnetic field will push the charges sideways to sideways, i.e., along the wire, giving an EMF and, if there’s a closed circuit, a current. This is probably the most common way of doing things.

answer

the arrows to the right of earth should point up.
