Near the Wire: The magnetic field is most intense close to the carrying conductor. Here, the field lines are densely packed, indicating a stronger magnetic effect. Away from the Wire: As one moves further from the wire, the magnetic field’s intensity diminishes. This decrease in strength is...
When such electrons are induced to move along a straight wire, a magnetic field is generated around the wire. The magnetic field is due to regions of vorticity in the primordial fluid around the wire. These regions result from a criss-crossing of fixed and moving ether springs. The fixed ...
Magnetic Fields – Learning Outcomes Demonstrate the magnetic fields in a magnet, long straight wire, loop, and solenoid. Describe these fields with particular emphasis on the vector nature of magnetic fields. Discuss Earth’s magnetic field and its use in navigation. 1 Magnetic Fi...

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 ...
Current-induced magnetic fields: (a) a straight wire and (b) a solenoid. The magnetic field of a solenoid is similar to that of a permanent magnet (shown earlier in Figure 17.1). This is not a coincidence. An electron orbiting around the nucleus of an atom is a form of charged ...
A magnetic field is avector, which means it has magnitude and direction. Ifelectric currentflows in a straight line, the right hand rule shows the direction invisible magnetic field lines flow around a wire. If you imagine gripping the wire with your right hand with your thumb pointing in th...
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...
