Electric Current Questions & Answers
What is your observation? An electric current passes through a straight wire in the direction of south to north. Magnetic compasses are placed at points A and B as shown in the figure.
The needles will deflect in the opposite directions
What is the definition of Biot-Savart Law?
The Biot Savart law is an expression of the magnetic field produced by a steady electric current. Deriving this law entails starting from Maxwell's equations, obtaining and solving Poisson’s equation for all three components of the vector poten
Why does current passing through a wire create a magnetic field?
Current flowing in a wire produces a magnetic field around the wire. In a coil, the field from the adjacent turns is the same direction, so it adds up. That is why a coil of wire makes a much stronger magnet than one with fewer turns. The magnetic fi
What units are used to measure current?
