Discovery of Electromagnetism
Right-Hand Rule
Findings
As the current passes through a straight wire the magnetic field wraps around the wire in concentric circles.
If we point our thumb along the direction of current (I) flow, our fingers curl around in the direction of the magnetic field lines (B).
This means a loop of wire must create a magnetic field which flows through the loop and around the outside!
Challenge: Amplify & Measure
How could we increase the strength of the field through a loop as shown above?
