1) A square coil with sides of length 0.4 meters, wrapped 35
times is placed in the x-y plane a magnetic field in the +z
direction. The magnetic field changes from 0.2 T to 1 T in a time
of 0.5 seconds. If the resistance of the square coil is 9 Ohms,
what is the average induced current produced in the current in
amps? If in the clockwise direction, indicate clockwise by
including a negative sign.

Consider a vertical plane in a constant gravitational field.
Let the origin of a coordinate system be located at some point in
this plane. A particle of mass m moves in the vertical
plane under the influence of gravity and under the influence of an
additional force f=-Ara-1 directed toward the origin (r
is the distance from the origin and A and a are constants). Choose
appropriate generalized coordinates and find the Lagrangian
equations of motion.

A circle with a radius of 0.3 meters is placed in the x-y plane
in a magnetic field directed in the -z direction. It is wound once
and its resistance is 6 Ohms. The initial magnetic field is 0.7
Tesla. The magnetic field is then changed in 0.4 s and the average
induced current is 0.04 amps running counter-clockwise. First, find
the final magnetic field to needed to induce this average
current.Then, the magnetic field (still in the -z...
