Electromagnetism, etc. Q & A
The figure below shows a compass and a magnet. Label the poles of the magnet and draw the field lines on the magnet. Q#22
The three diagrams show the field lines between the poles of two magnets. Identify the poles A, B, C, D, E and F as north or south poles. Q#23
Label the poles of the solenoid below if the current flows in the wire in the direction shown. Q#24
Draw the meter reading that you would expect in each of the following cases: Q#25
Describe the effect of the speed of the magnet on the electricity produced in the coil of wire. Q#28
Name one other factor (other than speed of magnet and number of loops) that could affect on the electricity produced in the coil of wire. Describe the effect(s). Q#29
Name one factor that affects the magnetic field induced in an electromagnet. Q#30
Name one factor that affects the magnetic field induced in an electromagnet. Q#31
Name one factor that affects the magnetic field induced in an electromagnet. Q#32
Name one factor that affects the voltage induced in the secondary coil of a transformer. Q#33
Name two applications of an electromagnet. Q#35
Explain the Fleming ’ s Left-Hand Rule and when can one use it? Q#36
What is a motor? Q#37
What is a generator? Q#38
Explain the Solenoid Rule. Q#39
Give two applications of the motor effect. Q#40
Give one energy source that uses the principle of electromagnetic induction to produce electricity and one energy resource that does not. Q#41
Applications of Electromagnetism
Faradays Law of Induction A changing magnetic field induces an electric field. The induced electric field causes a current to flow in a conductor.
AC vs. DC Current Electromagnetic Fields
Vocabulary Mini Review Magnetism. A(n) ___________ can be made by coiling a wire around an iron nail and connecting it to current. Electromagnet.
Unit IIA Magnetism Reference: Ch Essential Question: How is magnetism different from electricity?
Basics in Magnetism Electromagnetism Force on a Current-Carrying Wire EM Induction Transformer Generators Electric Motors ELECTROMAGNETISM.
Ch 8 Magnetism.
Transformer SONNY P. DE LEON MT 1.
Motion Current: Generating Electricity (Faraday’s law)
Magnetism Any time electrical power is moving through a wire magnetism is created Any time magnetism moves past a wire electrical power is created.
WHOLE BRAIN. Electric doorbells found in many homes require 8 V to operate. A transformer is used to convert standard household 120 V to the 8 V required.
UNIT FIVE: Electricity and Magnetism
Magnetism & Electromagnetism
Magnetism & Electricity Production. What is magnetism? Force of attraction or repulsion due to electron arrangement Magnetic forces are the strongest.
Prepared By: Shakil Raiman. If a current passed through a piece of wire held at right angles to the magnetic field of a magnet the wire will move. This.
Electricity and magnetism are different aspects of a single force: electromagnetism Electricity = result of charged particles Magnetism = result.
