Helmholtz coil lab report
WebThe Helmholtz coils of the e=m apparatus have a radius and separation of a = 15 cm. Each coil has N = 130 turns. The magnetic fleld (B) produced by the coils is proportional to the current through the coils (Ihc) times 7:80¢10¡4 tesla/ampere [B(tesla) = (7:80¢10¡4)Ihc]. A mirrored scale is attached to the back of the rear Helmholtz coil. WebThe magnetic field produced by the Helmholtz coils is proportional to the current. The number of turns in each coil is equal to N = 200 and radius of coils is equal to a = 0.1025 m. Using Eq. (1) from file "E5 - Description", calculate the calibration coefficient k of the Helmholtz coils and write it in your lab report.

WebHelmholtz coils. Check that the electron beam is parallel to the Helmholtz coils. If it is not, turn the tube until it is. Don’t take it out of its socket. As you rotate the tube, the socket will turn. 8. Carefully read the current to the Helmholtz coils from your ammeter and the accelerating voltage from your voltmeter. Record the values below. Web1 jun. 2024 · The windings of our Helmholtz coil was made of standard 0.95mm wire to provide the maximum possible current. The coil was powered by a function generator. Results: The Helmholtz Coils generated a uniform magnetic field between its coils. The magnetic field strength at the center of the space between two coils was 97.6 μT.
