PPT on topic Electromagnetic Force, useful for IGCSE/CBSE Physics students. This PPT was created as part of a session to be taken for inspection. This session is based on tasks and simulation.
1. • Think of anything you usually take for granted.
• Close your eyes.
• Imagine a day without it.
“Gratitude is pausing to notice and appreciate these things, it’s
taking a moment to reflect on how fortunate we are when
something good happens — whether it’s a small thing or a big
thing.”
2. To incorporate critical thinking and collaboration in analyzing the interaction between
magnetic field and electric current
Daily household items like electric motor, mixer grinder etc. works on this principle
Collaboration, experimentation, critical thinking, simulation
3. PRE-ASSESSMENT
1. The magnetic field lines surrounding a bar magnet forms
(a) Open loop (b) Closed loop
2. The magnetic field lines
(a) May intersect each other
(b) Never intersect each other
(c) Sometimes intersect each other
3. A current carrying straight conductor produce magnetic field lines in the shape of
(a) Sphere
(b) Concentric circles
(c) Parallel lines
4. The field lines inside a bar magnet
(a) Is from south pole to north pole
(b) Is from north pole to south pole
(c) Doesn’t exist
As magnetic field lines always form closed loop, a magnetic monopole doesn’t exist
(a) True (b) False
5. Two magnets can attract or repel.
If current element can produce magnetic field, does it interact with other magnet?
What are the practical applications of this?
6. KEY VOCABULARY
Fleming’s Left Hand Rule: Stretch the thumb, forefinger and middle finger of your left hand such
that they are mutually perpendicular. If the first finger points in the direction of magnetic field and
the second finger in the direction of current, then the thumb will point in the direction of motion or
the force
acting on the conductor
Alternating Current: Current which changes direction
7. You have the freedom to move through the lesson at your pace, for example, some of you
may have studied the lesson beforehand or seen a video, you can quickly move on to
progress check and activities.
Some of you may not be able to solve the questions in progress check tab ( which is perfectly
OK), you can go and refer to the resource again before you attempt the task again.
All of you can collaborate with peers and/or learn independently.
If you are unable understand any key content of the lesson, then you can always go back
refer to the content and continue with the lesson at your pace.
Please remember that with freedom comes a lot of responsibility. It is ultimately your
journey and you have to make sure you complete the learning objective before going into the
next lesson.
Self-Reflection on your learning skills.
