This problem deals with a current carrying wire that is placed in an external magnetic field at a particular angle and an experience is a particular magnetic force.
00:09
And then we want to figure out how long that wire is.
00:12
Well, just to visualize, it looks like we have a wire carrying a current eye.
00:19
It's going to be placed inside a external magnetic field and it's going to make a particular angle with that magnet field.
00:26
We're not given a picture.
00:27
We're just trying one, given the information we know.
00:30
It's going to be 50 ,000.
00:33
Between the current carrying direction and the direction of the external magnetic field.
00:37
Now we also know the force that is acting on this wire and we want to know and find out how long the wire is.
00:46
So if we look at our definition of the magnitude of the magnetic force acting on a current carrying wire, it's given by the current flowing through that wire, the length of the wire, the magnitude of the external magnetic field in which the wire is in, and multiplied by the sign of the angle between the current carrying direction and the magnetic field direction...
