    Magnetic Field and induced current

    Can anyone help me to do this problem. Thanks in advance. A closed wire loop in the form of a square of side 4.0cm is mounted with its plane horizontal. The loop has a resistance of 2.0*10^(-3) ohm. The loop is situated in the magnetic field of strength 0.7 T directed vertically downwards...

    Where is the neutral point between 2 wires

    There are 2 long wires A and B, placed 10cm apart. The currents in 2 wires are the same, 0.3A downwards. Where is the neutral point, how far is it from wire A?

    Perfect Crystal Brittleness: Fact or Myth?

    Thank you all. I'm studying solid material. And it's quite new things with me. In my notes, I wrote: Almost perfect crystals of material contain few dislocations to cause plastic flow. Therefore, they are strong but brittle. That's what physics teacher taught.

    Perfect Crystal Brittleness: Fact or Myth?

    My physics teacher taught me that, however, when I asked my chemistry teacher, he said NO. And now ... I'm confused. Plz anyone can help me to make me clear about this with explanation.?
