The strength of a magnetic field decreases with the distance from the magnet The strength of the magnetic field could vary inversely as the square of distance as with the strength of a gravitational field or an electrical field |
What is the maximum magnetic field of a permanent magnet?
- Pulse current pulse discharge, milliseconds can reach more than 100 ka, general pulse magnetizing device can provide the maximum magnetic field is about 6-10 t, in principle can be coercive force of 2400 ka/m of the permanent magnet material in the condition of demagnetization filling to saturation.
What is the strength of magnetic field far away from a wire?
- A straight wire of diameter 0.5mm carrying a current of 1A is replaced by another wire of 1mm diameter carrying same current. The strength of the magnetic field far away is- 35A current is flowing in long straight wire. Calculate the magnetic field at a point which is at a distance 20cm from the wire.
How do you calculate magnetic field strength?
- The formula therefore for calculating the “Magnetic Field Strength”, H sometimes called “Magnetising Force” of a long straight current carrying conductor is derived from the current flowing through it and the distance from it. H – is the strength of the magnetic field in ampere-turns/metre, At/m
What is the force of a permanent magnet?
- Most permanent magnets have magnetic flux densities B less than one Tesla (104gauss), so a magnet this powerful with an area A = 10 cm2(~the size of a silver dollar) would therefore apply an attractive force AF = 0.001×12/2×4?10-7 ?400N (~100 pound force).
