Faraday’s Law of Induction; Lenz’s Law problem solving
of wire in a magnetic field. A square loop of wire of side l=5.0 cm is
in a uniform magnetic field B=0,16 T. What is the magnetic flux in the loop (a)
when is perpendicular to the face of the loop and
when is at
an angle of 30° to the area of the loop?
What is the magnitude of the average current in the loop if it has a resistance
of 0.012 Ω
is rotated from position (b) to position (a) in 0.14 s?
a coil from a magnetic field. A 100-loop square coil of wire,
with side l=5.00 cm and total resistance is R=100 Ω, positioned perpendicular
to a uniform magnetic field B=0,600 T, as shown in Fig.
It is quickly
pulled from the field at constant speed (moving perpendicular to )
region where B drops abruptly to zero. At t=0, the right edge of the
edge of the field. It takes 0.100 s for the whole coil to reach the field-free region.
