A long wire with a radius of 0.400 cm carries a current. The
potential difference across a 3.70 m long section of this wire is
13.0 V, and the wire carries a current of 0.450 A.
A potential difference of 53 mV is developed across the ends of
a 12.0-cm-long wire as it moves through a 0.27 T uniform magnetic
field at a speed of 4.0 m/s. The magnetic field is perpendicular to
the axis of the wire.
What is the angle between the magnetic field and the wire's
velocity?
A wire 80 cm long carries 11 A of current. From this
wire, a loop of 90-turns is made and placed in a magnetic field of
6.50 Tat an angle of 35˚. In first experiment, a square loop is
formed and in the second experiment, a circular loop is formed with
same number of turns. Calculate the torque in each loop. Which loop
produces more torque-the circular loop or the square loop? What is
the reason for this change of...

An 8.00-cm-long piece of wire is formed into a square, and
carries a clockwise current of 0.150 A. The loop is placed inside a
solenoid, and the plane of the loop is perpendicular to the
