Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.
Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.
Further to the original answer, it is a voltage that is induced into a conductor, NOT a current.
Magnetic induction is the process in which an item is magnetized by an external magnetic field. The force of the fields comes from the poles of the magnet to produce the magnetism. The process is also called magnetic flux density.
To heat something by induction (which is and oscillating magnetic field), the material has to react to the magnetic field. As the magnetic field is made to oscillate, the molecules of the material are pulled and vibrated in sympathy with the field and their vibration energy increases. Heat IS the vibration of molecules. Thus induction heating will work on a magnetic material but will have no effect on a material that is not magnetically susceptible.

When the magnetic field is observed from the North pole, the magnetic field emerges and and goes towards south. However, inside a magnet there is no field at all, thus forming butterfly shape lines. Hence, B stands for butterfly and due to this concept, scientists used the symbol B for magnetic induction.
if there is no magnetic induction there will be no electricity
Magnetic induction and electromagnetic induction are used pretty much interchangably. Magnetic induction is really electromagnetic induction. One of the four fundamental forces in the universe is the electromagnetic force. Not the electrical force or the magnetic force, but the electromagnetic force. And magnetic induction is just another term for electromagnetic induction.
actually magnetic field is the region around magnet and magnetic induction is the process of using magnetic field to produce current , voltage etc'magnetic induction is basically force per unit length and current. from [fatima ]

Induction, which refers to induced voltage is related to magnetic field and area. Change of magnetic flux inside a wire loop caused a voltage to be induced or induction. A change in magnetic field or area changes the value of induction. Induction can also be considered a function of the current change rate.
For electromagnetic induction, you need a conductor moving in a magnetic field.
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
the magnetic domains that become aligned in the iron core contribute to the overall magnetic field of the coil and therefore increase its magnetic induction.
