What is the magnetic field due to an infinite linear current carrying conductor?
Magnetic field due to an infinitely long straight current carrying wire – definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.
What type of metal is not attracted to magnets?
Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic. Two metals that aren’t magnetic are gold and silver.
Which metal is the most suitable for making permanent magnet?
iron
How do you get a magnet to stick to aluminum?
You can fashion the aluminum into a tube, and drop the magnet through it. Eddy currents will produce a magnetic field that slows the magnet down, i.e. sticking to the magnet somewhat.
What is the formula for pole strength?
According to the pole strength formula, the pole strength of a magnet is given by the ratio of magnetic moment to its effective length (called the magnetic length).
What is unit of pole strength?
unit of pole strength is (1) Am^2 (2) Am (3) Am^-1 (4) Am^-2. Answer: (2) There are two possible units for magnetic pole strength in SI units, depending on how the pole force is described. If you describe this as force per unit field B, then the SI unit is the ampere-meter (A m).
What do you mean by pole strength?
: a quantity corresponding to the amount of magnetic flux emanating from a given magnetic pole and expressed in terms of the unit magnetic pole.
Is North Pole stronger than South Pole?
It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center. If you were to sprinkle iron filings on a piece of paper and place the magnet beneath it, you could see the path of the magnetic field lines.
