This chapter discusses the magnetic fields of a current loop. The chapter explores several possibilities to calculate the field components of current loops of radius. The chapter derives a solution using the law of Biot-Savart. The radial and axial field components B r , and B , of a ...

We can observe that the magnetic field lines are in the form of concentric circles near the sides of the loop but towards the centre of the loop, the magnetic field lines become almost parallel which indicates that this part of the coil has a uniformmagnetic field. In other words, we can...

A high-sensitivity magnetic transducer able to sense magnetic fields from dc up to tens of kilohertz is analyzed in this paper. The system is based on a nulling field coil fed by a current on the basis of the residual field, sensed by a magnetic sensor (Hall or magnetoresistive) placed ...
Why does a piece of iron in a current-carrying loop increase the magnetic field strength? Why does the length of current loop affect the magnetic force? Why is the magnetic field inside a solenoid stronger than one outside? Why do permanent magnets have a magnetic field?

Relatively few lines of the infinity of possibilities will close after one or a few turns; for them, the available magnetic energy can be sufficient to maintain the current high enough to keep the loop conductive. Most loops never close and cannot be excited by the finite magnetic field. ...
Therefore, the proposed dipole possesses a vertical polarization perpendicular to the metallic plane. Moreover, thanks to normal electric field, the proposed dipole is less affected by the ground plane size and surrounding metal. The proposed antenna topology provides a very easy way to realize ...
