The magnetic flux density at any point my be defined as the number of linese of magnetic induction passing through a unit area held a right angle to the lines at the point and is represented by the vectore
have a magnetic
if there is no magnetic induction there will be no electricity
temporarily magnetic
Put a piece of iron close to it, if it is magentic an atractive force will apear. If you want to distinguis what kind of magnetic properties your object has (ferromagnetic, paramagnetic),... then you should use a magnetometer like for example SQUID.
Electro magnetic induction...................
If the paper clip is made of a magentic metal such as steele, then you cn make it magnetic. If it is made of plastic or a non-magnetic metal, then you cannot.
Yes - in magentic terms, "hardness" = "permanence".
For electromagnetic induction, you need a conductor moving in a magnetic field.
If you mean electromagnetic induction, there are a lot of ways. For example, an alternator (that is a generator of AC current) works via electromagnetic induction. The headlights of a bicycle are powered via induction (bikes have a magnet in the wheels and when you pedal the magnetic field rotates thus creating current).
There is no element to heat to complete the circuit. Another example would be magnetic induction lighting.
The induction magnetometer detects temporal variation of the geomagnetic field based on Faraday's law of magnetic induction.
