Question

• Magnetic rlelu u Maguete muutto agnitude of the magnetic field along the axis of an N-turn coil (Helmholtz coil) is MONIR? B =- bontotos mori noturnos (222) - Assuming the solenoid has 500 turns, radius of 100.0 cm and carries a current of 10,0 mA What is the magnitude of the magnetic field at a point on the solenoid's axis 50.0 cm from the center? (Show work) - Assuming the field point approaches a very large value, what happens to the magnitude of the magnetic field? (Show work) What is the direction of the magnetic field in the solenoid in Fig. 7.1?! Fig. 7.1 Fig. 7.2 What is the direction of the magnetic field of the bar magnet in Fig. 7.2?

Answer 1

B = Mo NI R2 2 (n?+ R2) 312 s = 500 - 50cm = R- 100cm = I 10 mA 0.5 meter 1 meter UT Xlo Sobrio X10 2 [ (o.s)2 + W27/2 6.2832x10-6 2.79.5 l R = B 2.240 x 10-6 Tesla A field magnetic point field in will belone die very large dobu. AM
