A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...

MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
