Why is flour passed near a magnet before being packed?
Flour is passed near a magnet to remove any metal fragments that may have entered during the milling process. This helps ensure the flour is safe for consumption and prevents any potential damage to equipment during packaging.
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
Is a horseshoe electromagnet bar magnet or a magnet pole a example of a temporary magnet?
A horseshoe electromagnet is an example of a temporary magnet because it only exhibits magnetic properties when an electric current is passed through it. When the current is turned off, the magnetism disappears.
What would happen if a strong magnet passed an object with magnetic domains arranged randomly?
If a strong magnet passed by an object with randomly arranged magnetic domains, the magnetic domains in the object would align with the magnetic field of the magnet. This alignment would result in the object becoming temporarily magnetized in the direction of the magnet's field until the influence of the external magnet is removed.
Does a magnet conduct heat?
Yes, a magnet can conduct heat. Heat can travel through magnetic materials like iron, nickel, and cobalt because the thermal energy is passed along the magnetic domains within the material.
Why is flour passed near a magnet before being packed?
Flour is passed near a magnet to remove any metal fragments that may have entered during the milling process. This helps ensure the flour is safe for consumption and prevents any potential damage to equipment during packaging.
What happens when a strong electric field is passed through a permanent magnet?
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
How are magnet made?
Magnets are made by lodestone. If the magnetic qualities of lodestone are passed in a magnetic substance, then it will be a permanent magnet.
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
What is a law before it's passed?
It is usually called a "bill" before it is passed and while it is pending in the Congress or the state legislature.Read more: http://wiki.answers.com/What_is_the_name_of_a_law_before_it_is_passed#ixzz16Wxv6VJr
How many times does a forward text message get passed before it stops?

How a magnet could be used to separate different types of metals at a recycling centre?
A magnet can be used to separate ferrous metals (containing iron) from non-ferrous metals. When the magnet is passed over a mixture of metals, the ferrous metals will be attracted to the magnet and can be easily separated out. Non-ferrous metals, which are not magnetic, will not be affected by the magnet and remain in the mixture.
How does a dc dynamo work?
It uses a permanent magnet which is rotated by a crank. The spinning magnet is positioned so that its north and south poles passed by a piece of iron wrapped with wire. It was discovered that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. Furthermore, the north and south poles of the magnet induce currents in opposite directions. By adding a commutator, it is possible to convert the alternating current to direct current.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
How do salmon know where to go to migrate?
They just know. there brains are wired to know. its like a magnet.
Who named magnet?
Captain James Cook when he sailed passed it in 1770 and the island caused the ships compass to deviate.
