Asolenoid with an air core has a magnetic field pointing along its axis in the positive x direction. this solenoid is then filled with a diamagnetic material. what changes will this make to the magnetic field along the axis of the solenoid?

we can say that with a smaller magnitude , the field will point is in same direction

Explanation:

we have given that

solenoid is filled with a diamagnetic material and with air, magnetic field pointing along its axis in the positive x direction

so in small magnitude, the field will point is in same direction

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
