What are the factors affecting the electromagnetic induction?
Identify factors which affect the power of electromagnet?
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
What happen when you change the direction of current in an electromagnet?
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
What happens if the current of an electromagnet is changed?
The field strength of an electromagnet (and the shape of that field) will largely be determined by the physical characteristics and geometry of the coil (wire size, number of turns, spacing of turns, diameter of coil, etc.), the current flow through the coil's wire and the material and shape of the core. The most variable aspect of the electromagnet is the current we run through it. Once the electromagnet is designed and constructed, the limits are "built in" and about all we can vary is current. Use the link to the GSU Hyperphysics site and it's diagram of an electromagnet. (Be sure to scroll down a bit.) Also, look around on that site, if you have time. There is a lot of good basic physics there. The explanations are very reader friendly and the diagrams are pretty good, too.
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.

How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.

If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped

How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.

What must be done in the mass spectrometer to bring ion to the detector?
Change the strength of the magnetic field.
