said that one of the factors to determine the voltage(emf) that can be induced into the coil using just magnetism is by increasing the magnetic field strength so, how to increase the strength of the magnetic field?
Homework Answers
EMF is induced in a coil by changing magnetic flux which can be done in many ways .so magnetic flux is basically the productof magnetic field and area of loop . So EMF is induced by changing magnetic flux that can be done by increasing or decreasing magnetic field or by changing the area of loop . So strength of magnetic field can be increased by increasing the current flow in the loop or by increasing the no. Of turns in the loop .

question below?
A uniform magnetic field points directly into your paper (make a sketch). A 7 turn coil of wire with a radius of 14.2 cm lies in the plane of the paper. Over a period of 0.00035 seconds, the field is increased from 0.300 T to 1.10 T. How much emf is induced in the coil while B is changing?

A 35-turn coil has a diameter of 11 cm. Find the magnitude of the emf induced in the coil (in V) if it is placed in a spatially uniform magnetic field of magnitude 0.35 T so that the face of the coil makes the following angles with the magnetic field, and the magnetic field is reduced to zero uniformly in 0.2 s.

An emf of 0.45 V is induced between the ends of a metal bar moving through a magnetic field of 0.22 T. What field strength would be needed to produce an emf of 1.5 V between the ends of the bar, assuming that all other factors remain the same?
