Magnetic Forces, Fields & Distance — Drills · Grade 6 Science
Chapter: Electricity, Magnetism & LightWhat these drills covers
By the end of Magnetic Forces, Fields & Distance you should be able to:
- I can name which materials are magnetic and design a test to check a sample.
- I can describe a magnetic field and how its strength changes with distance.
- I can explain how an electromagnet differs from a permanent magnet.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: magnetic field, pole, evidence, system boundary, uncertainty.
Problem 1
- Every metal must be strongly attracted by a magnet.
- magnetic field: A representation of magnetic interaction around magnets or electric currents.
- Dividing a bar magnet creates an ordinary magnet with only one pole.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
magnetic field: A representation of magnetic interaction around magnets or electric currents.
A representation of magnetic interaction around magnets or electric currents.
Problem 2
- Every metal must be strongly attracted by a magnet.
- Dividing a bar magnet creates an ordinary magnet with only one pole.
- pole: A north or south magnetic orientation region in the simple magnet model.
- Repeating any method makes every causal claim true.
Answer and explanation
pole: A north or south magnetic orientation region in the simple magnet model.
A north or south magnetic orientation region in the simple magnet model.
Problem 3
Answer and explanation
No. The force may be too small to overcome friction or be detected by the procedure.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
A current-associated magnetic effect in the stated setup, with its detection limits; it does not establish every current strength or construction.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
