Okay so I want to make a telescope at home... Im not a noob. Even if I am please just help me. I've got a couple of magnifying glasses ..pretty big .. I don't know the exact focal length... But one of them is twice the size of other... As soon as the sun comes up I'll find their focal...

Are you serious ?I know it's OBVIOUSLY ZERO for any position.Read the title pls. And then as a mental exercise I invite you to think what does "Prove the mgn. field is zero" means .. [Hint: It means the magnetic field IS ZERO !] I know it is zero. I just need the solution . I can't find it...

wow... I really thought this site would be better than others. thanks for proving me wrong.

I obviously don't have that... Which is why I'm here..

I know its really easy for north and south pole like situation, but This is really different...and I'm not sure I follow your hint...

Can You be more specific ?

Okay yes . I am a noob. I want to know what all courses are out there that are related to physics ...classical non classical anything related to physics that I can take up in college ?

If Neutron stars are what they are... I mean made of literally only neutrons ...how do they generate such immense magnetic field (of the order 10^8 or something) .. I think the name is somewhat misleading and it ought to have a near half ratio of protons ...But still being so compact how...

A metallic sphere of radius R and specific resistance ρ is taken and two wires( negligible resistance) connected to it at random positions (say at an angle θ apart from each other.both the wires are perpendicular to the surface of the metallic sphere. Prove that the Magnetic field B at the...

Why is it that everything is so so different between the two worlds ...?
