Cork Screw Rule - Find Direction of Magnetic Field Lines For Current-carying Conductors and Coils

Cork screw rule is used to determine the direction of magnetic field lines.
As the magnetic field lines come out of the magnetic North pole and go into the magnetic South pole, the direction of the field lines tells us where magnetic N and S poles are.
A current-carrying conductor or coil creates a magnetic field in the surrounding space.
If the direction of the current is known, the cork screw rule allows us to find the direction of the magnetic field lines. (The conventional current flows in the circuit from the positive terminal of the power supply towards the negative terminal).
Please note that this is not the only way of finding the direction of the magnetic field lines. One alternative is the right-hand grip rule. The important thing is to learn one rule and apply it consistently to various situations.
Also, please note that the compass used in the video was a little demagnetized and not very responsive.

Thanks bro, I literally struggled at this and you cleared my queries with it, respect for you!

[@AbdullahiMohamud-or1fr]

Thanks for your clear explanation

sir i need urgent help may i contact you, how a electromagnet and permanent magnet react with each other , may we transform permanent magnet 's magnetic force in electricity (generate a motor) with the help of less powerful electromagnet then permanent magnet

[@ibphysicshelp]

I’m not sure that I understand the question but yes, you can use the magnetic field of a magnet to induce a current in a coil moving/rotating relative to the magnet. But remember, you cannot create energy out of nothing. In fact, it does not matter how you get the magnetic field (permanent or electromagnet) as long as you move the coil relative to the field you can create an electric current.

@@ibphysicshelp ok as you say we cant get electric energy directly by this method, but in this situation i have mentioned in upper comment, may we convert magnet's force in mechanical energy, suppose electromagnet rod/shaft is free to move/rotate in magnetic field, finaly my question is that the output result(mechanical moving) will be dependent on what less powerful electromagnet or more powerful permanent magnet , or electromagnet use more and more power According to permanent magnet power(magnetism)

Conversion of mechanical energy into electrical energy is done in a generator (that uses a magnetic field). The reverse, electrical energy in mechanical energy is done in a motor (which also makes use of an electric field.
You can have a loop of wire falling under the pull of gravity in a magnetic field and generate a current in the loop (also, a braking effect appears in this context)
