Example 3) Magnetic field around a Single Loop of Wire
+ (Positive Terminal)
- (Negative Terminal)
A loop of wire with current creates a little magnet
It either has:
The North Pole on the top of the loop and the South Pole on bottom
OR South Pole on the top of the loop and the North Pole on bottom
How to find the North and South Pole of a loop of wire
Step 1 - KNOW - Current travels from ________________ terminal, DRAW the direction of the current on the wire
Step 2 - Bring your hand to the loop and point your thumb in direction of ________________________
Step 3 - Curl fingers of left hand
Step 4 - Note where four fingers are pointing when they enter the
____________________of the loop
Fingers tips will point in the direction of the NORTH POLE of the magnetic field of the loop
For the loop pictured above, the North Pole is ABOVE or BELOW ??
Where's the south pole?? ABOVE or BELOW ??
