Explain why Ampere’s law can be used to find the magnetic field inside a solenoid but not outside.
3. An Atwood machine consists of two masses, mA
and m B, which are connected by an inelastic cord
of negligible mass that passes over a pulley. If the
pulley has radius RO and
moment of inertia I about its axle, determine the
acceleration of the masses
mA and m B, and compare to the situation where the
moment of inertia of the
pulley is ignored. Ignore friction at the axle O. Use
angular momentum and torque in this solution
A 0.850-m-long metal bar is pulled to the right at a steady 5.0 m/s perpendicular to a uniform, 0.650-T magnetic field. The bar rides on parallel metal rails connected through a 25-Ω, resistor (Figure 1), so the apparatus makes a complete circuit. Ignore the resistance of the bar and the rails. Please explain how to find the direction of the induced current.
