WebMagnetic fields. A solenoid produces a magnetic field only in the presence of a flowing current. Bar magnets produce a permanent magnetic field. Materials used for formation. Solenoids are formed from soft steel or iron. Bar magnets are formed from hard steel or iron. Strength of the magnetic fields. WebFeb 13, 2015 · Draw a line from the field point to the edge of the solenoid at z = z 1, and call the angle between this line and the axis θ 1. Define θ 2 similarly. (Note that these angles will be greater than π / 2 if z 1 < 0 or z 2 < 0, respectively.) Then the magnetic field along the axis will be proportional to ( cos θ 1 − cos θ 2).
WebThe energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills. Iron has a much, much larger permeability than a vacuum. Even small solenoids can exert forces of a few newtons.
