6. How could we use the experimental setup in Figure 3 to plan an
investigation that would test how the strength of a magnetic field
affects braking speed?
O We could use a swinging copper pendulum, and adjust the strength of
the electromagnet during different trials. By measuring the time it takes
for the pendulum to make a complete cycle, we could test how the
magnetic field effects braking speed.
We could use a swinging plastic pendulum, and adjust the strength of
the electromagnet during different trials. By measuring the time it takes
for the pendulum to make a complete cycle, we could test how the
magnetic field effects braking speed
We could determine how many paper clips the electromagnet can pick
up in order to determine the strength of the magnetic field. This would
tell us how quickly the braking might occur when applied to a braking
system.
We could determine how few coils the electromagnet can have before
it loses magnetic abilities. This would tell us the minimum magnetic
field strength it would require before applied to a braking system.
