3 Ways to Increase the Strength of an Electromagnet

First talk to your doctor to determine a healthy weight for you. Magnetic field created by a current edit The magnetic field created by an electromagnet is proportional to both the number of turns in the winding N and the current in the wire I hence this product NI in ampere -turns is given the name magnetomotive force.

Using magnet of high strength and increasing the number of turns in the solenoid the experiment is repeated.

. When the field is weakened the back-emf reduces so a larger current flows through the armature winding and this increases the speed. The strength of the magnet depends upon the iron content. Losing 3 lb 14 kg per week is a slightly faster rate than the recommended 12 lb 045091 kg per week but its possible.

Reducing the field strength is done by inserting resistance in series with a shunt field or inserting resistances around a series-connected field winding to reduce current in the field winding. Why did the galvanometer needle deflect in the experiment. So the maximum strength of the magnetic field possible from an iron core electromagnet is limited to around 16 to 2 T.

Then figure out how many calories youll need to burn each day and create this deficit using a combination of healthy eating and exercise. While you need a strong magnet to make another metal magnetic the magnetism produce will probably not be very strong. On the basis of the experiments complete the table 32.

As long as a metal has some iron in it you can magnetize it using another magnetic metal or an electromagnet. It will be sufficient to pick up a paperclip or a screw. Field weakening is not used on its own but in.

Whenever there is a change in the magnetic flux linked with a coil an emf is induced in the coil. To lose 3 lb 14 kg per week as an.
