In the figure below we have a wire loop with resistance R. in the gray area, magnetic field is constant and equal to B Figure1 We assumed that wire loop in the figure below has a resistance R so the current generated is : I=vBh/R But what if R=0 (perfectly conductive material) What happens when we move the loop with speed v?
A wire with resistivity ρ (resistance per unit length) is bended in a way to form a shape like bb-8 in the movie Star Wars. (See the figure on the right.) We can approximate it as two circles of radius R and 2R lying in the same plane. Note the wire has an insulating shell, and it crosses over itself at joint of the two circles. The wire is then placed in a magnetic field that is spatially uniform, but increases its magnitude over time with B = bt, where b is a constant of appropriate dimension. (a) What is the total resistance of the wire? Express your answer in terms of ρ and R. (b) What is the emf induced in the upper circle? In which direction? Express your answer in terms of R and b.

The earth's magnetic field, with a magnetic dipole moment of 8.0×1022Am2, is generated by currents within the molten iron of the earth's outer core. Suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter “wire.” The loop diameter is measured from the centers of this very fat wire. 1) What is the current in the current loop? 2) What is the current density JJ in the current loop? 3) To decide whether this is a large or a small current density, find the ratio of the current density JJ in the current loop to the current density of a 2.0 AA current in a 1.6-mmmm-diameter wire.
The problem below explores the basic principles behind electric generators, which we will discuss in class in detail. A 505 turn circular loop coil with a diameter of 3.9cm is initially held perpendicular to the Earth's magnetic field. The coil is then rotated in 7.6ms by 90 degrees, so the plane of the coil is parallel to the magnetic field. The average emf induced in the coil is 7.2V. Find the value of the Earth's magnetic field (in T) inducing the current in the coil.As an approximation, assume that the magnetic flux in the coil changes at a constant rate between its maximum and minimum values. Note that (see the previous problem) the flux through the coil is 505 times larger than if it was made out of one wire loop.
As the lesson discussed, electromotive force (in volts) is generated by a change in flux. This induced voltage, , is given by the formula, in wire loops where current can flow. Remember, flux is the product of magnetic field and area: In this picture below, the magnetic field is pointing out of the page. The "loop" is on the right. As the bar moves to the left, the flux of the loop because the area of the loop increases. Current is induced to oppose this change in flux, generating an induced magnetic field that . Therefore, the current will .
