Question
Answer the following question:Be sure to show all work. Include formulae and units.Be sure to include relavant, meaningful diagram and a complete circuit diagram with circuit related problem. take enough space, don't try to squeeze everything on a small space!(problems are from:principle of physics:calculus based; Chapter: Magnetic forces and Magnetic field)
Q.n.6) A circular loop of wire with a radius of 0.8cm carries a current of 6 A.The loop is in a region of space where the magnitude of the magnetic field is 0.03T.The orientation of the loop:The angle, Theta, is 600 and the current is flowing out of the page to into the page indicates the direction of the current in the loop.
Indicate the direction of rotation on the diagram.
Explanation / Answer
formula for magnetic field B due to circular current is given by
B = uoi/2R
where i is currnt
R is radius
uo is constant = 4pi e-7
so to find the direction of Torque , formula is T = NIA B sin theta
where N is No . of turns
i is current
A is area
B is magnetic fied
so find the direction of torque , use RH rule ,
RH rule says that if the three fingers of right hand are streched in three mutual perpendicualr axes
and ifore finger indicates the direction of magnetic field
Middle finger indicates the direction of current
then thumb indicates the diurection of torquw on the loop
as currentin inwards, loop will movei Clockwise direction
