A conductor of length 10 cm carrying 2.5 A current is placed in a magnetic field of 0.5 T. Calculate the maximum and minimum forces on the conductor. What is the force on the conductor when it is placed at `45^(@)` to the direction of field?

Explanation

`l=10cm=0.1m, I=2.5 A, B=0.5T`
`" "F=BIL sintheta`
`" "F_(max)=BIL " "("when "theta=90^(@))`
For `theta=45^(@) " "F=0.5 times 2.5 times 0.1 sin45^(@)=8.83 times 10^(-2)N.`
