Best Answer

factors on which magnetic field a bar magnet depends :-

1. pole strength of the magnet

2. medium in which the bar magnet is present(since the permittivity changes)

factors on which external magnetic field(B) of a current carrying coil depends:-

1. the amount of current flowing through the conductor

2. the perpendicular distance of the point from the conductor.

3. medium in which the conductor is present(since the permittivity changes)

What is the difference between magnatic field strength and pole strength?

Pole strength is ability of poles to produce lines of force where is field strength is force which a magnetic poles experiences when places in magnetic field.


What does the relative density of lines of a magnetic field tell us about the strength of the field?

The closer the lines the stronger the magnetic field.


How do you reduce the strength of magnetic field?

you spread them apart.


Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.?

No. More current will result in more magnetic field.


What is the unit to measure the strength of a magnetic field?

We can say magnetic field strength is a measure of magnetic strength of a magnet.. like electric field density in electrostatics.... ex consider a current carrying wire which produce a magnetic field in radial direction... by using ampere law.. we can easily find magnetic field strength at a point (r distance from wire)... H=I/(2*3.14*r).. its like finding a electric field intensity by Guass law.......The magnetic field ranges from less than 30 micro-teslas (0.3 gauss) to 60 microteslas (0.6 gauss) The strength varies daily usually about 25 nanoteslas (nT) with variations every second of 1 nTAnswerMagnetic field strength (symbol H) is defined as the magnetomotive force per unit length of a magnetic circuit, and is expressed in amperes per metre (A/m). The original answer appears to be defining flux density(expressed in teslas), not magnetic field strength.
