The program functions as a school-within-a-school, where the magnet serves as a secondary program to tát the main comprehensive program.

Such magnets, therefore, require regular topping-up with liquid helium.

Also, cement dust has entered the switching contacts, magnets and the organ pipes themselves.

The use of a magnetic core can enormously concentrate the strength and increase the effect of magnetic fields produced by electric currents and permanent magnets.

The magnetic field can be generated with a superconducting magnet filled with liquid helium.

The train then re-enters the station and is stopped by the magnetic brakes.

A magnetic field parallel to tát the filament is imposed by a permanent magnet.

In essence, spin waves are a propagating re-ordering of the magnetisation in a material and arise from the precession of magnetic moments.

The beam deflections were driven by magnetic coils, and those coils fought against rapid changes to tát their current.

A fusion reactor used to tát power a ramjet starship might be a steady state magnetic fusion reactor based on the following nuclear fusion reactions.

This remanence is carried by minerals, particularly certain strongly magnetic minerals lượt thích magnetite (the main source of magnetism in lodestone).

Greater voltage creates more magnetism pulling the solenoid's core in further against the spring loading, moving the pointer.

This theory united all previously unrelated observations, experiments and equations of electricity, magnetism, and optics into a consistent theory.

Using the principles of magnetism, these brakes slow down the falling gondola gently, yet rapidly, without actually contacting the gondola.

All substances not possessing one of the other types of magnetism are diamagnetic; this includes most substances.

These particles were to tát be magnetized in accordance with the alternating current from a microphone source.

The filmmakers used a secret chemical for flesh and hair, and the characters had magnetized feet.

The blocks are then heat-treated, cut to tát shape, surface treated and magnetized.

The piece can be magnetized by direct or indirect magnetization.

A ferrofluid is a liquid which becomes strongly magnetized in the presence of a magnetic field.

The rest is lost in the process, dissipating in magnetic flux that is not picked up by the receiving coil.

Beyond this region, energetic ions populate the plasma sheet to tát the dayside magnetopause filling the faintly sketched magnetic flux tubes to tát higher latitudes and contributing to tát the ring current.

The core is then passed through the work-piece and when the primary coil is energised, a magnetic flux is created around the core.

The oscillation frequency is determined by the maximum magnetic flux mật độ trùng lặp từ khóa, the power supply voltage, and the inductance of the primary winding.

In the rotating coil, the magnetic flux changes because the orientation changes.
