COMEDK2023PhysicsMagnetic Effects of Current
A straight wire of length 2 ~m carries a current of 10 ~A . If this wire is placed in uniform magnetic field of 0.15 ~T making an angle of 45^ with the magnetic field, the applied force on the wire will be
Options
- A1.5 ~N
- B3 ~N
- C3 2 ~N
- D3 / 2 ~N
Correct answer
D. 3 / 2 ~N
Step-by-step solution
Given, aligned & i=10 ~A , B=0.15 ~T , & =45^ and l=2 ~m aligned Here, F=i l B =10 2 0.15 45^ = 3 2 ~N
