MAGNETIC FIELDS SUMMARY Solenoids are cylindrical windings of wire. Currents through solenoids create magnetic fields inside that are uniform (in the case of a perfect solenoid) and directed along the axis of the solenoid. In this lab the field at the center of a solenoid will be measured, and from the results the vacuum permeability constant μ, will be calculated. You will then induce a voltage in a coil using a handheld magnet, and from the result determine the strength of the magnet's magnetic field. THEORY The magnetic field B at the center of a circular coil (solenoid) of radius R with N turns that carries a current I is Bcenter Ho NI 2R (1) where μ, is the vacuum permeability constant, μ = 4 x 10-7 T-m /A. The magnetic field at the center is directed along the axis of the solenoid and mostly uniform. Instead of a current creating a magnetic field inside the coil, a current can be induced by changing the magnetic flux inside the coil. One way to do this is to change the magnetic…

Problem3 Your textbook calls the electric generator "probably the most important technological application of induction." Let's consider an example of such a generator, consisting of a single round loop of wire of R 100 Ω. The loop is rotated at a frequency f of 60 turns per second (and thus at 60x 2π radians per second). As shown in the figure below, the rotation axis of the loop is through its diameter and perpendicular to the page, and the loop rotates clockwise. We place the loop in a uniform magnetic field of strength B 0.50 T that points to the right. Note that the loop is arranged so that its rotation axis is perpendicular to the field. The angle θ measures the angle between the field and the normal onto the plane of the loop.
