Please help me if you can...
question: Use the following quantities to calculate the magnetic field strength of the horseshoe magnet.
Mass of coil: 20 grams
current in coil: 2.0 amps
length of bottom of coil: 10cm
angle coil makes with vertical: 30 degrees
Hint: Equate magnetic force on bottom of coil to the horizontal componen of the coils weight.
The question also adds that there are at least 3 assuptions made in answering this question.
I've got a diagram

I don't know where to start in the calculating process Can someone please help me with the starting point and i'll try and progress from there...this is the first time I've seen a problem like this
