# Finding magnitude of magnetic field in a conducting coil

## Homework Statement

A conducting coil of 1830 turns is connected to a galvanometer, and the total resistance of the circuit is 41.0 . The area of each turn is 4.70 10-4 m2. This coil is moved from a region where the magnetic field is zero into a region where it is nonzero, the normal to the coil being kept parallel to the magnetic field. The amount of charge that is induced to flow around the circuit is measured to be 8.87 10-3 C. Find the magnitude of the magnetic field. (Such a device can be used to measure the magnetic field strength and is called a flux meter.)

Magnetic flux=BAcos(theta)
emf= -N(magnetic flux / time)
B=N(4pie-7)I / (2r)

## The Attempt at a Solution

I'm not sure where to start, I have my equations, but it almost seems like I have been given the wrong set of information. Either that or I am missing an equation?
