Change In Voltage The Amount Of Emf
1,731 wordsPlanning Aim To find the factors that affect the amount of E.M.F. being produced. The amount of E.M.F. produced during the experiment when each type of factors is change. Background knowledge Electro-motive-force is the energy being supply to a charge. Battery is a type of energy. The energy that it provides is voltage. Battery voltage is sometime called electro-motive-force because it is used to "pump" around the electrons in the wire. The force can be generates by the moving of magnetic field ...

More Iron Filings
1,223 wordsPhysics - Electromagnetism Planning Previous Scientific Knowledge. When insulated wire is wrapped round an iron nail and the ends of the wire are connected to a battery the nail becomes capable of picking up iron filings and paper clips. This is called an electromagnet. The nail is magnetised by the current in the wire. If the battery is disconnected then the iron clips will fall off. This is because most of the magnetism has been lost. The passage of an electric current along a wire creates a m...

Time O The Paper Clips
822 wordsWhat Affects the Strength of an Electromagnet? Aim What is the effect of increasing the current and increasing the number of coils when picking up paper clips? Definition First of all, an electromagnet has to be defined. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then wire is wrapped round it. Prediction I predict that as the current carried in the wire gets stronger, so will the magnetic field surrounding the electromagnet. Therefore, I think that the a...

Coil Of Wire A Magnetic Field
902 wordsWhat factors affect the strength of an electromagnet? Introduction I will be testing the factors which will make an electromagnet stronger. Electromagnets are magnets which are created and are easily controlled by electricity. All magnets have a region of space around them called the magnetic field which exerts a force on any magnetic material such as iron and steel or any other magnet which enters it. This force can be attractive and repulsive. If an electric current flows through a coil of wir...

Factors Affecting Strength Of Magnetic Field Of An Electromagnet
1,442 words. Investigating the factors affecting the strength of an electromagnet. Background Knowledge: The theory of magnetism is the only way to explain the process of magnetizing an object. In an unmagnetised piece of iron the domains are pointing in numerous directions, which results in them cancelling each other out. However, a magnetized piece of iron would have all the magnetic domains pointing in all the same direction. This is due to the north poles being at one end and the south poles at the oth...

Number Of Coils Within The Magnetic Field
304 wordsThe parts of a motor are a team working together to convert electrical energy into mechanical energy. The parts, their descriptions and how they work are explained below: Armature The coil is wound onto a frame called an armature. It is usually made of ferromagnetic material (something that conducts magnetism well). The armature is usually free to rotate an axle called the armature axle. This sticks out of the motor and rotates with the coil and is used to do the work the motor is designed for. ...
