Magnetic Field of a Moving Charge, Proton, Right Hand Rule - Physics & Electromagnetism

This physics video tutorial explains how to calculate the magnetic field of a moving charge such as a proton. It explains how to determine the direction of the magnetic field of a moving proton using the right hand rule and the i j k technique. You need to find the cross product of the velocity and position vectors.

A little late but a good tip for knowing direction of a magnetic field if the proton is going in or out of the page is to think of it like a screw. Lefty loosy righty tighty. If you are loosening a screw to come OUT, you turn it LEFT, if you want it to go IN, you turn it to the RIGHT

Tremendous blessings to you, friend. You're my academic angel. Please stay safe. We all need you <3 My best to you and yours.

genius. cleared my concepts so well i am grateful

Another conclusion you can draw from your point at 8:10 is when you do right hand rule, you can use your left hand if the charge is negative. So if you have an equation where your "q" is negative, or if the problem states its an electron, rather than a proton, use the same rules as you do with your right hand but on your left

Broo, do you know how much knowledge you have? Now imagine the sun and the moon is local and they are our positive and negative charge of earth's Magnetic field. This is what Tesla understood. I'm trying to figure all this out now. You literally got the brains man

Dear Sir, can you make a video about Biot-Savart's Law?

0:33 if an electron is located at point A, what's the force it will experience?
How those particles affect the relative magnetic permeability of the space around them?

You can actually derive this using Maxwell equations. By calculating the change in electric field per time of a loop

[yshnav]

what is the procedure when V AND B directions are given and we need to find clockwise or anticlockwise direction of the proton

[pghislain]

One comment: you say, the magnetic field is "moving". I believe we should use the term "curved", the magnetic field is curved arround the moving charged particule. The image of the clock is missleading and the curve B vectors are also a abusive representation (curved vectors does not exist !).

[adosar]

yes but doesnt magnetic field needs time to propagate at point A ? so how we know the magnetic field ?
