What concept describes the force on a current-carrying wire in a magnetic field?
The
motor effect
View source
What determines the direction of the force on a wire in a magnetic field?
The directions of the magnetic field and
current
View source
How can you determine the direction of force on a wire using Fleming's rule?
By using
Fleming's left hand rule
View source
What happens to the force direction if the current direction in a wire is reversed?
The force direction also
reverses
View source
What occurs when two wires are connected at one end in a coil with current flowing?
The left side experiences an
upwards
force
The right side experiences a downward force
The coil starts to spin
clockwise
View source
What happens to the current direction when the coil is rotated by 180 degrees?
The current travels in the
opposite direction
View source
What is the effect of the current direction change on the forces acting on the coil?
The
forces
on
each
side
swap
direction
View source
What happens if the coil keeps flipping back and forth without intervention?
It won't complete a
360-degree
rotation
It won't be useful for practical applications
View source
What device is used to change the direction of current every half turn in a motor?
A
split ring commutator
View source
What does the split ring commutator do in a motor?
Swaps
positive
and
negative
connections
View source
How does the split ring commutator affect the coil's rotation direction?
It ensures the coil rotates in the
same direction
View source
What are the practical applications of electric motors?
Fans
Vehicles
Hard drives
View source
What is the fundamental principle behind electric motors?
Creating spinning motion using electricity
View source
How can the speed of an electric motor's rotation be increased?
Increase the
current
Add more turns to the coil
Increase
magnetic flux density
View source
What is one way to increase the power of an electric motor?
Increase the
current
passing through the wire
View source
What is another method to enhance motor performance?
Add more turns to the
coil
View source
What can be done to increase the magnetic flux density in a motor?
Use more
powerful
magnets
