Magnetic Effects Of Current Question 49
Question: A cell is connected between two points of a uniformly thick circular conductor. The magnetic field at the centre of the loop will be [MP PMT 1994]
Options:
A) Zero
B) $ \frac{{\mu_{0}}}{2a}(i_{1}-i_{2}) $
C) $ \frac{{\mu_{0}}}{2a}(i_{1}+i_{2}) $
D) $ \frac{{\mu_{0}}}{a}(i_{1}+i_{2}) $ (Here $ i_{1} $ and $ i_{2} $ are the currents flowing in the two parts of the circular conductor of radius ?a? and $ {\mu_{0}} $ has the usual meaning)
