The sketch shows the coil lying in the plane of the screen and
the external magnetic field pointing into the screen. As the
external magnetic field decreases, an induced current flows in the
coil. What is the direction of the induced magnetic field caused by
this current? 
Homework Answers
as the external magnetic field is decreasing , hence in according to Len's Law induced current must strengthen the external magnetic field.
To strengthen external magnetic field magnetic field due to induced current must be " pointing into the screen "
Direction of induced magnetic field : pointing into the screen.

An external magnetic field is parallel to the central axis of a 65.0-turn coil of radius 7.50 cm. During an interval of 156 ms, the field changes from 0.180 T in one direction to 0.340 T in the opposite direction. The resistance of the coil is 70.0 Ω. What is the average induced current in the coil during this interval?

A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.61 V and a current of 3.2 A are induced in the coil. The wire is the re-formed into a single-turn square coil, which is used in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the same rate). What emf and current are induced in...
