This question refers to the phenomena of making a washer rise when it is in a superconducting state. This is a popular science demonstration experiment.
Normal superconductors will not allow the penetration of a magnetic field into its interior. This is accomplished by creating a current distribution on the surface that is arranged to exactly cancel the externally created field in the interior of the superconductor.
The induced current is an electromagnet and has an external magnetic field. As with any magnet, there is a force then between the electromagnet and the external magnetic field source. They repel and the washer moves.

How do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
What happens to the hole of the washer when heated?
When a washer is heated, the hole will expand in size due to thermal expansion. This means that the diameter of the hole will increase as the washer absorbs heat. Cooling the washer will cause the hole to contract back to its original size.
How do you put cable from battery through firewall in 1999 mercury sable?
Drill a hole and then insulate the hole with a rubber washer so the cable doesn't chafe on the jagged hole.
What is the magnetic field of a black hole?
A black hole has no magnetic field.
How can electricity produce by using magnet?
Electricity is generated when a piece of conductive metal (such as copper) is passed through a magnetic field (or if the magnetic field is moved around the metal). A generator will have a copper wire in the center, surrounded by a magnet shaped like a torus (donut shaped, wire is in the hole in the middle). The wire is stationary. Electricity is generated when the magnet is spun (moving the magnetic field around the wire). This will generate an AC current (alternating current).
How do you repair a singing toilet when flushed?
Replace to inlet washer this normally happens when the washer develops a hole
Starting with the top mounting bolt on a coil-over shock system what is the order or parts washers gaskets etcfrom top to bottom mounting bolt?
On the shock you will have a washer and a grommet on top, then put it through the mounting hole and put on a grommet then washer then nut. Its a grommet sandwich with the mounting hole being the meat.
What is a reducing washer donut?
A reducing washer is used when the wrong size knockout gets removed. If you have a 1/2 in connector that you have to mount into a distribution panel and all there is left is a 3/4 inch hole that has already been punched out, you would use a reducing washer to reduce the 3/4" KO hole down to a 1/2" KO hole. You would put one washer on the outside of the panel hole and the other one on the inside of the over sized panel hole. Install the connector through both of the washers and tighten the connector's lock nut on the inside of the panel. These washers are not to be confused with reducing bushing that are used to reduce a hub size down to a smaller size.
What makes a shower head low flow?
In most there is a washer in them that has a small hole in it so that only so much water can get through regardless of how much pressure is behind it.
What is the bearing stress between the timber and the four by four square steel washer if the hole is seven eights diameter?
To calculate the bearing stress between the timber and the steel washer, you need to know the applied force or load. Once you have the force, divide it by the contact area between the timber and washer, which is the area around the hole. The contact area can be calculated as the outer diameter of the washer minus the diameter of the hole, multiplied by the thickness of the washer. Finally, divide the force by the contact area to find the bearing stress.
Was there ever a coin made that was a little smaller than a 50 cent piece that was blank with a square hole in the middle and made out of copper or is it something else hole is perfectly square?
It's a WASHER, possibly a torque washer.
