This would be applicable for an electromagnet. Pulsed just means the field is applied for a short time. It's easier to make a really high field if you do it this way because of power supply limits, Ohmic heat buildup, or material strength limits (magnetic fields apply a great force to the coil). Some applications don't need the field on for very long, and you can get fields *much* higher this way.

The strongest lab magnets are permanent, superconducting, and pulsed magnets. Permanent magnets retain their magnetism for a long time.
A pulse magnet provides very high magnetic fields as high as 72 T.
Pulsed magnets provide brief, but extreme magnetic fields. Their average life expectancy is between 500 and 800 pulses.
Hope this answer helps!

a pulsed magnetic field i think is produced by an electromagnet
to which signals are given in pulses.. like a pulsating DC current whose current value keeps varying almost sinusoidally but only that it never changes the direction.........

Simplest terms a field that is turned off and on. It would be like someone playing with a light switch
