Hello ,
The speed at which an object with the ski will move down the slope is determined by the net acceleration . The net acceleration is quite complex to determine but it depends on the gravitati

induction in solenoid wire |
| Question: | |
hi. thank you so much for helping me.
Q: we have a solenoid with magnetic core inside. a magnetic field B that is going through the core is changing (no mangetic field lines are passing through the wire of the coil. magnetic field lines exist only in the core. so the change in B exist only in the core). will there be any induced current in the coil wire ?!

Induced Electromagnetic force will be in coil. As the flux changes Induced electromagneticforce too will change and induced current will flow if coil wire is a closed circuit.
