very helpful

[@HardySingh-gk2wr]

Sir, firstly I'd like to appreciate your videos, they've been very helpful for me.
Secondly, in Q30, although I get the entire method of solving the question, the only confusion I am facing is that shouldn't we apply the LEFT HAND RULE for conventional current, and apply this with the right hand ONLY IF electronic current or the flow of electrons is specified?
Because in the video, we have applied the LEFT HAND RULE WITH THE RIGHT HAND, even though we are supposed to consider conventional current.
According to my understanding, if we apply the left hand rule instead, the answer will turn out to be A.
Please explain. Thank you.

You apply the left hand rule when a current is already flowing the coil/wire that has already been set in the magnetic field of the magnet. That current induces a magnetic field which interacts with the magnetic field of the magnet to produce a force.
You apply the right hand rule when you are moving the coil/wire at right angles through the magnetic field of a magnet and that induces a current in the wire. An example of using the right hand rule would be in the AC generator.

Sir I don’t understand Q1 why it is not C ?

[@ferhanmazher]

In head to tail rule resultant force is you join the tail of the first vector with the head of the last vector. C is not the answer of question 1,
