# Magnetic Force

Not what you're looking for?

A wire 2.80 m in length carries a current of 5.00 A in a region where a uniform magnetic field has a magnitude of 0.390 T. Calculate the magnitude of the magnetic force on the wire assuming the angle between the magnetic field and the current is (a) 60.0, (b) 90.0, (c) 120.

##### Solution Summary

This solution uses equations for force, specifically the scalar version, to find the magnitude.

##### Solution Preview

For a straight wire in a magnetic field, the force is given by:

F = I(LXB)

Here, the force, length, and manetic field are all vectors, and X represents the cross-product. (The length vector is a vector with the magntude of the length ...
