Just like we have solar n lunar eclipse. What is the name given when all the bodies in our solar system alligns in one line? And what are the effects of it on earth?
now how if the same solenoid (which is made up of another solenoid) i.e the 1st solenoid is hollow in the inside and we have a liquid metal flowing within it? (considering fluidity, waves, magnetohydrodynamics)
What would be the magnetic field of a solenoid if the wire of the solenoid itself is made up of another solenoid? I would be glad to hear any explanation about it.
