A straight wire carrying a 2.88-A current is placed in a uniform magnetic field of magnitude 0.274 T directed perpendicular to the wire. Find the magnitude of the magnetic force on a section of the wire having a length of 13.9 cm. N

When the current in a long, straight, air-filled solenoid is changing at the rate of 2000 A/s, the voltage across the solenoid is 0.600 V. The solenoid has 1200 turns and uniform cross- sectional area 25.0 mm2 . Assume that the magnetic field is uniform inside the solenoid and zero outside, so the result L =M0AN2/l applies. What is the magnitude B of the magnetic field in the interior of the solenoid when the current in the solenoid is 3.00 A?
