Which law of electricity is Biot Savart law of magnetism analogous to?
Biot-Savart law in magnetism is analogous to Coulomb’s law in electricity. According to Biot Savart law, magnetic flux density
which is analogous to the electric field
which is Coulomb’s law.
Name one property that cannot be calculated using the Biot Savart law.
Electric field intensity cannot be calculated using the Biot Savart law. It is used for calculating the magnetic field intensity. This is further used for calculating the flux density and permeability using the formula
Consider a circular conductor with 2m radius and 8A current flowing through it. Determine the magnetic field intensity at the centre of the circular conductor.
By using the formula
we can determine the magnetic field intensity.
Substituting the values for current I = 8A and radius R = 2m, we get B =
What is the magnetic field at the centre of the conductor when the conductor is subjected to a current of 9A and with infinite radius?
The formula used for calculating the magnetic field is
Since R is infinite, the magnetic field will be 0.
