Calculation of transformer inductance value
I am trying to find a way to calculate the primary and secondary inductance of transformer.
I learned that it is changing from one topology to another. My topology is Phase-Shifted Full-Bridge ...

Does hysteresis still occur if saturation is not achieved in a core?
When looking at a BH curve, what happens if the H field is raised to some level below saturation. For example we apply an H field that is only half way to saturation. On a BH plot this will trace a ...

Can a slanted magnetic field be created with this insulated stranded wire arrangement?
I am considering building a small-scale experimental coil gun because I have an idea of how a magnetized projectile could be rotated while it is traveling through the coil(s), similar to how a bullet ...

High magnetic permeability material at 100MHz
I'm doing experiments as a hobby and was trying to find a material with good (very good) magnetic permeability at least at 100 MHz (higher frequencies are even better). Ideally the material would have ...

Magnetic lines geometry inside a dc motor
How are the magnetic lines of the armature and stator field distributed? Are they always perpendicular to each other or do they align in every half cycle (while the rotor is rotating)? I suppose that ...

If I have two magnets repelling each other, will they always form a peak in the middle?
If I have two identical magnets, aligned so they repel each other a distance of X apart and at a height of Z I have Hall effect sensor, the peak of the magnetic field sensed will be at the distance X/...

Example problem of induced emf in a coil travelling with some velocity and perpendicular to the earth's magnetic field
I have a example problem which I created myself just out of curiosity,
Question:
Let's say a copper wire coil(20mm dimeter(r=10mm)) of 3 turns(N=3) is moving along the surface(Note-coil is not ...

Magnetic field generated by a current-carrying wire
When dealing with the magnetic field generated by a current-carrying wire, the formula for the magnetic flux density is B = μi/2π·d, but what if the point is located on the wire it self?
In this case ...
