Question

Force experienced by a current-carrying conductor placed in a magnetic field is largest when the angle between current and magnetic field is

• A. $0^{\circ }$
• B. ${90}^{\circ }$
• C. ${45}^{\circ }$
• D. ${180}^{\circ }$

Answer 1

The correct option is B

${90}^{\circ }$

The force experienced by a current-carrying conductor is largest when the directions of the magnetic field and electric current are perpendicular to each other. i.e. the angle between the current and magnetic field is ${90}^{\circ }$.
