    Investigating Factors that Affect the Strength of an Electromagnet Aim: To investigate the factors‚ which affect the strength of an electromagnet‚ also known as it’s‚ pick up power. Predictions: The more coils of wire used on the electromagnet then the greater number of paper clips picked up. Also The greater the current the greater the number of paper clips picked up. There will also be a limit to the amount of magnetism created and how many paper clips can be picked up

    An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices‚ such as motors‚ generators‚ relays‚ loudspeakers‚ hard disks‚ MRI machines‚ scientific instruments‚ and magnetic separation equipment‚ as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron. A simple

    Investigating Electromagnets Aim: The aim of the experiment is to investigate what affects the strength of an electromagnet. Hypothesis: The more coils and electricity the more powerful the electromagnet becomes. Prediction: When the voltage of electricity is increased I think that the nail will have more magnetism allowing it to attract more paper clips‚ because with more voltage going through the circuit‚ it can then make the electromagnet stronger. Variables: Independent The independent

    Explain what it means when we say a substance is magnetic. A substance can be picked up by a magnet. Discuss the relationship between electric and magnetic fields. The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab‚ you need to form a hypothesis that reflects which material‚ voltage‚ and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement. If I use copper‚ 100 volts‚ large thickness
