Increasing the number of coils in a solenoid or an electromagnet results in a ___ magnetic field.

Stronger Magnetic Field

Explanation:

The magnetic field in a solenoid is given by

where B=magnetic field

Permeability

n=no of turns per unit length

I=Current through solenoid

When No of turns increases, it increases the strength of the magnetic field.  

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
