These Bitesize pages will help if you need to recap on the basics of magnets. A magnetic field is produced whenever current flows through a wire. The magnetic field is represented by a series of concentric circles around the wire, as shown below. Magnetic field lines around a current carrying wire. image: physick wiki The direction ...

The period T of a simple pendulum can be calculated using where l is the pendulum length and g is the gravitational field strength. Using a single value of length and period, we can determine the acceleration due to gravity. However, it would be better experimental practise to vary the length of the pendulum and ... Read more
I have attached revision notes from Scholar for the Electromagnetism unit. Your test will be after the Easter holidays.
You should be thinking about getting some of your project report finished so there is less to do when the deadline approaches. You can start writing up your underlying physics section and sort out the references you will include at the end of the report. I’ve attached a guide on referencing in the Vancouver style. ...

The Q&W unit assessment is next week. Here are the Scholar notes to help with your revision.
Twinkle, twinkle little star, How I wonder what you are. Giant thermonuclear reaction; Held by gravitational attraction. Twinkle, twinkle little star, You look so small ’cause you’re so far. As you burn through constant fusion, Your twinkle’s just an optical illusion. That happens when your light gets near; distorted by our atmosphere. Twinkle, twinkle little ... Read more
Our Sun is a typical yellow star, so its emission would be represented by the middle star in this image. image courtesy of kstars, kde.org – colour is exaggerated The colour of a star also tells us something about the expected behaviour of a star, it’s lifetime, and destiny. This is achieved by plotting stars ... Read more
You will need the attached file when we go to the library to learn about using Excel to crunch data for your project.
