Magnetic Fields of Coils Lab

The video tutorial guides viewers through an experiment to investigate the axial magnetic fields of single and dual coils at various distances. It provides step-by-step instructions for setting up the experiment, collecting data, and analyzing results to calculate the permeability of free space. The tutorial emphasizes the importance of correct wiring and measurement techniques to ensure accurate data collection. It concludes with advice on writing the lab report.

What is the primary objective of the magnetic fields of coils lab?

• To measure the resistance of coils

• To investigate the axial magnetic fields of coils

• To calculate the speed of light

• To determine the voltage across a coil

What is the first step in setting up the single coil experiment?

• Connect the power supply to the coil

• Measure the diameter of the coil

• Attach the magnetic field sensor

• Level the track

How should the magnetic field sensor be prepared before starting the experiment?

• Attach it to the power supply

• Place it at the end of the track

• Set it to radial sensitivity

• Zero it with the tare button

At what current increments should the magnetic field strength be measured during the single coil experiment?

• 0.2 amp increments

• 0.05 amp increments

• 0.1 amp increments

• 0.5 amp increments

What is the maximum field strength location in a single coil setup?

• At the edge of the coil

• At the center of the coil

• Outside the coil

• At the power supply

What is the purpose of adding a second coil to the experiment?

• To increase the resistance

• To measure the voltage drop

• To investigate the combined magnetic field

• To decrease the current

What should be ensured when connecting the two coils in series?

• The coils are at different heights

• The current flows in the same direction

• The current flows in opposite directions

• The coils are of equal size

What should you do if the magnetic field graph does not stay positive during the two-coil experiment?

• Decrease the distance between coils

• Switch the two terminals in the second coil

• Replace the magnetic field sensor

• Increase the current

At what distances should the two-coil process be repeated?

• 1.5 times and 0.5 times the coil radius

• 1.5 times and 1 times the coil radius

• 2 times and 1 times the coil radius

• 2 times and 0.5 times the coil radius

What is the final advice given in the lab video?

• Double-check all measurements

• Try not to get wound too tight when writing your lab report

• Submit the lab report on time

• Ensure all equipment is turned off
