In this experiment you will make an electromagnet. Then you will test how changing two variables can affect its strength. Safety: Electromagnets can get hot
It is the magnetic force obtained in the solenoid after finishing the stroke using standard power . Remanent Force: It is the force remaining after switching
8 déc. 2021 should be de-attachable from both the Power supply and the electromagnet side to facilitate easy transportation.
Describe how the students could build an electromagnet. Include in your answer how the students should vary and test the strength of their electromagnet.

Magnets and Electromagnets. Can you make a magnet from a nail some batteries and some wire? Problems. Research. Can the strength of an electromagnet be
As current in the electromagnet varies so does the force on the compass needle. Electricity flowing through a wire creates a magnetic field around that wire.
A student is investigating the strength of electromagnets. Figure 1 shows three electromagnets. The student hung a line of paper clips from each electromagnet.
14 juil. 2016 The approach of this research paper is to find out the effect of the temperature on the strength of electricity.
POWER SUPPLY OPTIONS: • Front panel mounted indicator lights. • AC pilot light (Input voltage “ON”). • DC pilot light (Indicates magnet power "ON").

(Total 6 marks)M1.(a) in a longitudinal wave the oscillations / vibrations are parallel to the direction of energy
transfer. accept wave travel for energy transfer throughout 1 in a transverse wave the oscillations / vibrations are perpendicular to the direction of energy transfer. 1 (b) accept any sensible suggestion eg a vibrating drum skin does not move the air away to create a vacuum (around the drum) 1 (c) Level 3 (56 marks): A detailed explanation linking variations in current to the pressure variations of a sound wave, with a logical sequence.
