Answer 1

A constant magnetic field creates an electric field.

Step-by-step 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 2

A moving magnetic field creates an electric field.

A moving electric field creates a magnetic field

Step-by-step explanation:

Magnetic Field is the concentration of magnetism that is created around a magnetic charge in a given space. It is the magnet that creates the magnetic field, just as it is the electric charge and the mass that, respectively, create the electric and gravitational fields.

The origin of the magnetic field is in the movement of electrical charges. When the electric field oscillates in some region of space, this oscillation gives rise to a magnetic field oriented in a direction perpendicular (90º) to the electric field. To better understand the properties of the magnetic field, we make use of a feature known as induction lines, through which we can better visualize the shape of the magnetic field.
