Why does magnetic flux not pass through the hole in the washer?
Wiki User
∙ 11y ago
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.

What is the magnetic field of a black hole?
A black hole has no magnetic field.
Do black holes have a magnetic charge?
A black hole can have an electric charge if it swallows electrically charged objects, but no objects that we know of have magnetic charge. Magnets always have both a north pole and a south pole; there is no evidence that one can exist alone. A lone north or south pole would be called a magnetic monopole, and would have magnetic charge. If we discovered a magnetic monopole and fed it to a black hole then the black hole would gain the magnetic charge.
The hole you look through in a door?
Peep hole
Can a black hole have magnetic pole shift?
There is no supportive evidence for the conjecture of magnetic poles within a black hole. Consequently, there is no rational for a magnetic pole shift within a black hole. While poles are apparent within a black hole, these poles appear to be more gravitational (or due to the rotational nature of its internal accretion disc) rather than magnetic and, in many cases, are accompanied by relativistic jets emitted along the poles, which carry away much of the energy. However the mechanism for the creation of these jets is currently not well understood. Note: While there was a recent interpretation of a vast magnetic field for the discovery of the gamma-ray bubbles about the central of the Milky Way galaxy. However, according to the researchers, these magnetic lobes originate not from our galaxy's central supermassive black hole (Sagittarius A), but from intense star formation activity in a zone around the Milky Way's nucleus measuring approximately 650 light-years wide.
Are you supposed to have a hole in your bellybutton?
well...not a hole but your bellybutton may cave in or out, but not a hole. It would go right through you! !

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 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.
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
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 difference between clip on and pierced earrings?
The main difference between the magnetic and the clip-ons are how they look. Clip-ons are okay for dangly, hoops, or large earrings. However if you want small earrings or studs, you should stick with magnetic earrings because the small clip-ons tend to look either childish or grandmotherly.
Why won't my Craftsman 917 27110 go forward or backward?
Try this: All the way at the rear you will see a metal panel with a skeleton key-type looking hole (large and round at the top and then it narrows and gets straight at the bottom). There is a rod that comes through the hole, it is spring loaded. Pull the rod through the large round part of the key hole and on the rod you will see along the rod a built in washer-type ring. Make sure the washer-type ring comes through the hole and push it down to the small end of the key hole so it will stop it from going back through the hole. This engages the transmission. It is called the "free wheeling rod." To disengage the transmission, to make it easy to push, you pull out the spring loaded free wheeling rod and lift it up so it will go back through the large round part of the key hole. I would try this first. Mike
