Surface and subsurface discontinuities d. A The magnitude of this magnetic field decreases with increasing distance away from the wire. Which of the following equations accurately describe a magnetic field that can produce a constantly increasing emf in a loop perpendicular to its direction Justify your answer for each of the proposed magnetic fields.

None of the above. The charge must be in motion. The flow of liquid iron at the centre of the Earth generates an electric current that produces magnetic fields.

The magnetic field through a loop can be changed either by changing the magnitude of the field or by changing the area of the loop. The magnetic field created by current following any path is the sum or integral of the fields due to segments along the path magnitude and direction as for a straight wire resulting in a general relationship between current and field known as Amperes law. This self-sustaining loop is known as the geodynamo.

Electric and magnetic fields can be treated independently only if they vary in time. The charge must be positive. The following are the three sources of magnetic fields.
