Which change will most likely increase the strength of a mechanic field produced by an electromagnetic?

Increasing the number of turns in the coil of wire will most likely increase the strength of the magnetic field produced by an electromagnet. More turns of wire will result in a stronger magnetic field due to the increased current flowing through the coil.


Do doorbells have electro magnets in them?

Yes, most doorbells have an electromagnet inside them. When the doorbell button is pressed, the circuit is completed, activating the electromagnet which causes a hammer to strike the bell or chime, producing the ringing sound.


Is a electromagnet only charged when electric current passes through?

Basically, yes. However, especially when the electromagnet uses iron, it will most likely have some residual magnetism when the current is switched off. Note: You shouldn't used the word "charged" in this context. That refers to electrical charges, and is not usually used for magnetism.


Can electromagnets move not metals?

Electromagnets can attract or repel various materials besides metals. Materials that contain iron, nickel, or cobalt are generally the most responsive to electromagnets, but other materials like certain ceramics or even liquids can also be affected depending on their magnetic properties. The extent to which an electromagnet can move non-metal materials will depend on the specific properties of the material and the strength of the magnetic field generated by the electromagnet.


Which metal is not used as a electromagnet?

Most metals. eg Aluminium, copper, tin, uranium
