Maglev - Wikipedia

Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.Along certain "medium-range" routes (usually 320 to 640 km [200 to 400 mi]), maglev can compete favourably with high-speed rail and airplanes.

AC motor - Wikipedia

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.

Magnetic Equipment Guide -- Eddy Current Separators

In general, magnetic steel components such as chutes, framing, idlers, and pulleys should not be used within two to three feet of the magnet’s face and 1/2 to 1 foot of the magnet sides and top. Instead, non-magnetic manganese or stainless steel can be used in these areas. Some belt magnets use multiple magnets inside the self-cleaning belt.

A novel magnetic fluid shock absorber with levitating magnets

Relative motion between the two parts is damped by a shear force resulting from the flow of the magnetic fluid, which reduces the oscillation and extension of the moving parts. In recent years, the viscous properties of magnetic fluid are also used in the tuned liquid damper (TLD) to enhance the performance of the TLD [13, 14].

12.4: Magnetic Force between Two Parallel Currents

The ratio F/l is the force per unit length between two parallel currents \(I_1\) and \(I_2\) separated by a distance r.The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and other plasmas. The force exists whether the currents are in wires or not.

Uses of Magnets in Our Daily Life | Sciencing

Mines use magnetic sorting machines to separate useful metallic ores from crushed rock. In food processing, magnets remove small metal bits from grains and other food. Farmers use magnets to catch pieces of metal that cows eat out in the field. The cow swallows the magnet with its food; as it moves through the animal's digestive system it

Maglev windmill project report - SlideShare

Using a pair of permanent magnets like neodymium magnets and substantial support magnetic levitation can easily be experienced. By placing two magnets on top of each other with like polarities facing each other, the magnetic repulsion will be strong enough to keep both magnets at a distance away from each other.

Repulsive force (magnetism) | Article about Repulsive

The same force also acts in the axial direction on the conduction electrons in a wire moving in a magnetic field, and this force generates an emf in the wire. The emf in an element of wire of length dl is greatest when the wire is at right angles to the B vector, and the motion is at right angles to both. The emf is then given by Eq. (16).

Magnetic field and Magnetic force

The magnetic force is the force of attraction or repulsion that arises between electrically charged particles due to their motion The magnetic force between two moving charges may be described as the force exerted upon their charge by the magnetic field created by the other. This force causes the magnets to attract or repel one another.

Types of Motors - Classification of AC, DC & Special Motors

These electric motors are powered using a single-phase or three-phase alternating current. The basic working principle of AC motor is the rotating magnetic field (RMF) generated by the stator winding when an alternating current is passed through it. The rotor (having its own magnetic field) follows the RMF & starts rotation.

For continued rotation, the electromagnet allows the rotor field to reverse the polarity of its magnetic field (Fig. 1B) producing repulsion. The repulsive force between the poles repels the electromagnet along its path of motion.

Can I produce electricity by using permanent magnets with no

We have not the ability to move electrons freely through a magnetic field. If you can create an electron cannon then you can do this without any moving parts. However the power needed to do this would well exceed the usable current you would produce. Also this theory is flawed as electrons are the moving parts that create a current in wire.

Repulsive force (magnetism) | Article about Repulsive force

The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them. As with electric charges, the effect of this magnetic force acting at a distance is expressed in terms of a field field,
