How do moving charges produce magnetic fields?
A charged particle moving without acceleration produces an electric as well as a magnetic field. It produces an electric field because it's a charge particle. But when it is at rest, it doesn't produce a …
What is the difference between the magnetic $H$-field and $B$-field?
43 In layman's terms, E and B are the total electric and magnetic fields. D and H are the free electric and magnetic fields. P and M are the bound electric and magnetic fields. M would be the magnetic field …
Magnetic field due to a coil of N turns and a solenoid
Sep 3, 2017 · First of all let's derive the expression for the magnetic field at the axis of a current carrying coil Let's begin with a coil of a single turn and derive the expression for the magnetic field on the axis …
electromagnetism - Relation between Electric and magnetic fields ...
A magnetic field is caused by a moving electric charge correct? The moving electric charge causes an increase in the electric field in front of it and a decrease in the electric field in back of it, and these …
Can someone please explain magnetic vs electric fields?
A moving magnetic field will interact with the electric field it generates with the electrons in a current. If i could take any object with a net charge, (i.e. a magnet), even if it's sitting still and not moving, isn't …
How are compasses influenced by a magnetic field?
Apr 2, 2022 · Like magnetic poles repel, and unlike magnetic poles attract each other. Therefore the north pole of the compass needle points to the south pole of the bar magnet, and vice versa. But …
Why can't magnetic field lines intersect with each other?
Feb 9, 2020 · It is true that magnetic field is a vector, and if you have two magnets, the resultant field is the vector sum of the fields from each magnet. But that isn't what your teacher is talking about when …
magnetic fields - How to determine the direction of induced current ...
Aug 10, 2015 · The magnetic field has both a strength (how close the field lines are together) and a direction (the direction the iron filings point, combined with the orientation forwards/backwards …
Why is light called an 'electromagnetic wave' if it's neither electric ...
This field of energy is what we call "the electromagnetic field'. In other words, "light" is the transportation of energy from one part of the electromagnetic field to another, and it facilitates the interaction …
electromagnetism - EMF induced due to moving rod in magnetic field ...
Jun 17, 2020 · In generally all high school physics books under the chapter "Electromagnetic induction", the analysis of induced EMF in moving rod in uniform magnetic field is taken using Faraday's Law.
