Short Answer 1. A solenoid is connected to an ammeter. The solenoid is 6 cm long and has 300 coils. The resistance of the whole wire is 10 ?. Into the solenoid, a cylindrical magnet (diameter-l c n) is shoved, north pole first. The core of the solenoid has a diameter of 3 cm. A) If the magnetic field passing through the core of the solenoid changes 4 T/s, then what is the induced current in the solenoid? B) What...

You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of...
You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of induction to make some current flow in the wire. First, you pull the copper wire into a circular loop. Then you hold the bar magnet 15 cm above the center of the loop, parallel to the loop so that there is...
