What is the motor effect?
The force experience by a wire carrying a current that is placed in a magentic field
1 of 6
Why does the wire experience such force?
Because the current in the wire creates a magnetic field around the wire and this interacts with the magnetic field between magnets.
2 of 6
What happens when the wire is parallel to magnet?
The force is zero
3 of 6
When is the force on the wire the greatest?
When the wire is right angle to magnetic field
4 of 6
3 Factors that effect the force experienced by a current carrying conductor in a magnetic field?
Magnetic field strength, Length of the wire, current
5 of 6
What is the formula?
Force on conductor carrying current at right angle to magnetic field(N)=Magnetic Flux Density(T) x Current(A) x Length(m)
