Question

B is the magnetic field and i is the current passing through a semi-circular wire find Force
​

Answer 1

Force on a wire is defined as iBL

• Where i is current B is magnetic field and L is projected length.

• The value of L is R+R=2R

Hence force on wire is →

iBL Putting the values we get

F=2BRi

Final answer →→ 2BRi
