Respuesta :
To reduce the strength of an electromagnet, Juan must reduced the number of loops in the wire.
What is electromagnetic field strength?
The strength of an electromagnetic is the effect or force that an electromagnet exerts in a given field.
The strength of an induced emf in a given magnetic field is given by;
emf = NBA/t
where;
- N is number of turns of the magnet
- B is magnetic field strength
- A is area of the coil
Decrease in number of turns of the wire, reduces the strength of the magnetic field.
Thus, to reduce the strength of an electromagnet, Juan must reduced the number of loops in the wire.
