Magnetic Force Between Wires in a Circuit. An ENGR 100 team has designed an induction circuit for their project with a layout that places two parallel wires running between the light bulb and the coil a distance d = 20.0 cm apart. They measure a current of I = 0.5 A, flowing around the circuit (from the coil to the light bulb and back).
Assuming the parallel portion of the circuit may be described by long straight wire sections, and the permeability of free space, μo = 4 Π(10^-7) Tm/A.
a. Sketch the FBD
b. Find the magnitude of the force per unit length between the wires; is it attractive or repulsive.

Obtain what is the internal resistance (in ohms) of a 12 Volt car battery whose terminal voltage drops to 7.5 Volt when the starter draws 30 Amp
The rear axle of a truck is 2.5 m long. If the truck is moving at 28 m/s and the vertical component of the earth’s magnetic field is 3.2 *10^-5T, what emf is induced between the ends of the axle?
A small rubber wheel is used to drive a large pottery wheel, and they are mounted so that their circular edges touch. The small wheel has a radius of 2.9cm and accelerates at the rate of 7.9rad/s^2 , and it is in contact with the pottery wheel (radiu..
Raindrops are falling straight down at 11 m/s when suddenly the wind starts blowing horizontally at a brisk 5.0 m/s. From your point of view, What is the angle
A series RLC circuit contains the following components: R = 3.00 102 ?, L = 3.50 102 mH, C = 5.00 µF, and a generator with ?Vmax = 2.20 102 V operating at 80 Hz. Calculate the individual maximum voltages across the resistor, inductor
A 0.31 MeV x-ray photon collides by an electron and scatters straight back the way that it came. What is the kinetic energy of the scattered electron? What is the energy of the backscattered photon? Suppose that it was initially at rest.
What is the lowest possible kinetic energy of the atom in the box and what velocity does the atom have in the absence of such a measurement?
A certain type of laser emits light that has a frequency of 5.4 x10^14 Hz. The light, so, occurs as a series of short pulses, each lasting for a time of 2.7 x10-11 s.
The crates of weight 1490N will move with speed 2.2m/s at the top of a ramp that slopes downward at an angle 21.0^\circ. The ramp will exert a 533N force of kinetic friction on each crate, and the maximum force of static friction also has this val..
