I dont understand this question at all- could someone please help- at least giving me a starting point- thanks(adsbygoogle = window.adsbygoogle || []).push({});

A wire, of length 70cm is placed into a magnetic field of strength 0.001T. If the wire carries a current of 5 amps

1/ Calculate the magnitude of the forces on the wire if it is successively oriented at 900, 550, 350 and parallel to the magnetic field

2/ Draw a graph showing the variation of the force as the angle changes

3/ What will be the shape of the graph if the force is plotted against sin0

4/ Draw a graph of force against sin0

I know for the first one you have to use F=BILsin0 but i dont understand the co-ordinates- what angle am i supposed to use- What does 900, 550 and 350 mean???? I think if i get this first bit understood then i will be able to complete the other parts.

Thanks
