What does Fleming’s Left-Hand Rule help determine?
Think about how the fingers are used in this rule.
True or False: A conductor experiences the maximum force when it is parallel to the magnetic field.
Consider the angle that gives the greatest force.
What does Fleming’s Left-Hand Rule determine?
Think about the components of the rule and what they indicate.
If a conductor carrying 10 A of current experiences a force of 5 N in a magnetic field of 1 T, what would be the length of the conductor?
Rearrange the formula for finding length.
A wire of length 2 m carries 3 A of current and is positioned in a uniform magnetic field of strength 0.25 T at an angle of 60 degrees. Calculate the force acting on the wire.
Use the sine of 60 degrees in your calculation.
How would the force on the wire change if the angle of the magnetic field changed from 60 degrees to 90 degrees? Explain your reasoning.
Consider how the sine function behaves with angles.
