PROBLEM #1: PERMANENT MAGNETS 2 Choose a point near the pole of a magnet At that point draw a vector representing the magnetic field The length of the vector should give an indication of the strength of the field Keep in mind that: The field can have only one value and direction at any point
A quadrupole magnetimparts a force proportional to distance from the center This magnet has 4 poles: X Consider a positive particle traveling into the page (into the magnet field) According to the right hand rule the force on a particle on the right side of the magnet is to the right and the force on a similar particle on left side is to
Sketch of the magnetic ?eld due to an ideal in?nitely thin permanent magnet The thickdark line represents the ideal magnet while the dotted line outlines the corresponding physicalmagnet We will use this approximation to determine the magnetic ?ux of the bar magnet
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).
