... Now hold the bottom of the magnet about 1 cm above the top of the coil with magnet and coil axes aligned. Start collecting data and drop the magnet all the way through. Get a trace and store this data. Predict what will happen to the size and shape of the display if the magnet were moving with great ...

... coming out of the two pickups are added together, the fundamental has a strong signal. For the seventh harmonic, the pickup on the right is at an antinode, getting a lot of signal, and the pickup on the left is at a node, putting out little signal. When the signals are added together, this harmonic ...

Lesson 15 and 16
... The electric current produces a magnetic field and generates a total magnetic flux Φ acting on the circuit. This magnetic flux tends to act to oppose changes in the flux by generating an EMF that counters or tends to reduce the rate of change in the current. The ratio of the magnetic flux to the cur ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
