Magnetism I Torque on Current Carrying Loop In Uniform Magnetic Field All the best! 1. A current carrying loop placed in a uniform magnetic field experience- a net torque but no net force a net force but no net torque both a net force and a net torque neither a force nor a torque None 2. A current loop in a magnetic field- experiences a torque whether the field is uniform or non-uniform in all directions can be in equilibrium in one orientation can be in equilibrium in two orientations, both the equilibrium states are unstable can be in equilibrium in two orientations, one stable while the other is unstable None 3. A circular coil of 25 turns and radius 12 cm is placed in a uniform magnetic field of 0.5 T normal to the plane of the coil. If the current in the coil is 6 A, then total torque acting on the coil is- zero 3.4 Nm 3.8 Nm 4.4 Nm None 4. Assertion- The deflecting torque acting on a current carrying loop is zero when its plane is perpendicular to the direction of magnetic field.Reason- The deflecting torque acting on a loop of magnetic moment m in a magnetic field B is given by the dot product of m and B. Both Assertion and Reason are true and Reason is the correct explanation of Assertion Both Assertion and Reason are true but Reason is NOT the correct explanation of Assertion Assertion is true and Reason is false Assertion is false and Reason is also false None 1 out of 4 Time's up
