Given the current carrying wires shown below, indicate the direction of the magnetic field at points A, B, C, and D. Magnetic field near an electric current-carrying wire:To find the magnitude and the direction of the magnetic field created by a curre...
Magnetic fieldFinite hollow cylinderOblique solid angleA conceptually simple result, which was recently derived for the circulation of the magnetic field created by a finite portion of wire carrying a slowly varying current, is used with the superposition principle and symmetry considerations to obtain ...
Force on a current-carrying wire in a magnetic field: F=IlBsinΘ The force on a wire in a uniform magnetic field depends upon the current, length of wire in the field, magnitude of the magnetic field, and the angle...
magnetohydrodynamic and ferrohydrodynamic effects are taken into account in their analysis, and the magnetic field is created by a current-carrying wire. When the Rayleigh number, nanoparticle volume fraction, and magnetic number are increased, an increase in heat transfer is seen. Heat transfer is...
The ratio of the magnetic field at the centre of a current carrying coil of the radius a and at distance 'a' from centre of the coil and perpendicular to the axis of coil is View Solution A long staright wire of radius a carries a steady current I. The curent is unifromly distribut...

One of the simplest problems in magnetism is that of a long straight wire carrying a current i. The magnitude of the magnetic field B(r) at a perpendicular distance r from such a wire is given by the following equation: [11]Br=μ0i2πrlong straight wire Two long parallel wires carryin...
1. Understand the Magnetic Field Formula: The magnetic field B at a distance r from the center of a circular coil of radius R carrying a current I is given by the formula: B=μ0IR2(r2+R2)3/2 where μ0 is the permeability of free space. ...
In order to compare our reconstruction to the expected resulting field from a current carrying solenoid, a calculation of the 3D magnetic field was done by dividing a description of the solenoid into 0.1 mm long straight wire segments and calculate the field contribution from each segment in ...
