What happens when you put a current carrying conductor into a magnetic field?
Magnetic field around conductor interacts with the magnetic field of the magnet
What happens when current flows through a conducting wire?
magnetic field produced
Which way does magnetic field go?
North to south
What happens if there is no current flowing through the conductor?
No magnetic field
What happens if you increase current in magnetic field?
Magnetic field gets stronger
When does the motor effect occur?
When a wire with current flowing through it is placed in a magnetic field and experiences a force
How can the size of a magnetic field be increased?
-Increasing current
-Increase magnetic field size
-Greater length of wire
-Place wire at 90• to the direction of magnetic field
What is Magnetic flux density?
How strong a magnetic field is around a magnet
Unit for magnetic field strength?
Tesla (T)
Equation for Magnetic field density?
F = B I L
F=force (N)
B=Magnetic field strength (T)
I=Current (A)
L=Length of wire (m)
