electromagnetic field

does anyone know if i were to combine two opposite electromagnetic fields together, also if i were to put together two electromagnetic fields. what would happpen and are there any resources i could read?
much appreciated if someone would help

 

Electromagnetic fields are radio waves. How do you propose to "combine" them. Radio waves do not combine, they simply exist in the same space at the same time.

 

That's pretty much how universal electric motors operate.

 

Electromagnetic fields are vector fields, they add like vectors. They can cancel each other out. Any basic E and M book will cover all of this, or most introductory physics texts. This is true if they are static or dymanic ( like radio waves ). The two different fields are related to each other by equations know as Maxwell's equations.

 

According to Star Trek, it would be the end of the universe.....

I think you would just get cancellation if the E fields are opposite polarity and equal magnitude.

 

Motors use magnetic fields.

 

Which are still electromagnetic at low frequency.

 

True in a strictly technical sense. But it's the magnetic part of the field that does the work. The electric part of the field has no effect on the motor operation.
