Effects on the strength of the electromagnet Purpose To increase the current and increase the number of coils when picking paper clips. Definition First you need to define an electromagnet. An electromagnet, also called a solenoid, consists of a core and is then wound around a wire. In prediction, it is predicted that the magnetic field around the electromagnet will become stronger as the current in the wire becomes stronger. Therefore, I think that the number of paper clips picking up will increase with increasing voltage until the electromagnet can not pick up the paper clip.
The method reported in this study is to find the effect of temperature on the electrical, magnetic and electromagnet strength. We use magnets, electromagnets and electricity in our daily lives. Every time these things deal with the temperature. In our experiments, we found that the material properties (magnets, electromagnets, electricity) increase and decrease as the temperature rises or falls. Or, their attribute values may be constant. To find this, we used powerful magnets made with neodymium, electricity, and powerful electromagnets. It is also used to cool magnet cooling devices and heating parts. Please use the wire with the known resistance value. After the experiment, the performance of all these materials changed greatly.
In the case of an electromagnet, after a pair of electromagnets are made, the battery power is passed. This time we will measure its strength. The strength is 10000 gauss or 1 tesla. Having an output of 1 T at room temperature, lowering the temperature continuously decreases the strength of the electromagnet. When the temperature decreases by 24 to 0 ° C, the strength is reduced to about half. Then place the dry ice on the electromagnet. The temperature of dry ice is around -60 ℃. The strength of the electromagnet is remarkably lowered, and the measured value is close to 3000 Gauss
In the case of electromagnets, the higher the electromagnet becomes, the stronger it becomes. It shows average results at room temperature and has minimal on dry ice. When the electromagnet is placed in a cold place, the resistance of the electromagnet decreases, and as the resistance decreases, the flow of voltage decreases, so the power used in the system also decreases. Therefore, the strength of the electromagnet decreases. In high temperature magnets, extremely strongly bound atoms start to split and take time when they move completely freely. Therefore, most of them are excited so the magnetic field is perfect. As the cooling atoms shrink, their magnetic field adds several factors. There are several different types of magnets whose power decreases slightly with increasing temperature. Lowering the temperature reduces the resistance of the wire by the current through the wire.
