Physics experiments on magnetism
Station experiments from the basics to para- and diamagnetism
In 14 different stations your whole class can explore the elementary properties of magnetism as well as novel experiments in the field of dia- and paramagnetism. With the included checklist for students, all experimental results can be directly recorded and evaluated.
All topics in one case:
- Elementary properties and interaction of magnets
- Magnetic properties of materials in everyday life
- Explaining magnetic phenomena with models
- NEW: Diamagnetism and paramagnetism (e.g. Moses effect)
- Properties of magnetic fields
- The Earth’s magnetic field and the compass
Special equipment:
Neodymium magnets for the exploration of dia- and paramagnetism (see picture below)
Magnetic field model to demonstrate the properties of magnets (see picture above right)
-
1 - When do two magnets attract one another? When do they repel one another?
experiment "When do two magnets attract one another? When do they repel one another?"
The students each use two small bar magnets to investigate the attraction and repulsion of permanent magnets of comparable strength. To do this, the small bar magnets are brought closer to each other in the four possible orientations.
-
2 - Who is attracting whom here?
experiment "Who is attracting whom here?"
The students discover that iron attracts the magnet as well as the magnet attracts the iron and thus open up the principle of interaction.
-
3 - Where is the magnetic force strongest?
experiment "Where is the magnetic force strongest?"
The students examine the strength of the magnetic force at different points along a large bar magnet.
-
4 - Which materials stick to a conventional magnet?
experiment "Which materials stick to a conventional magnet?"
The students examine the material properties of metals and everyday materials. To do this, they use a small bar magnet and first observe the magnetic force acting on the five specified metal strips made of iron, aluminum, copper, nickel and zinc by observing whether these objects stick to the magnet.
-
5 - Which materials respond to a magnetic force?
experiment "Which materials respond to a magnetic force?"
The students use a strong neodymium magnet to discover the paramagnetic and diamagnetic properties of aluminum and graphite.
-
6 - The Moses effect
experiment "The Moses effect"
The station first demonstrates that diamagnetic and paramagnetic forces also act on liquids.
-
7 - How can magnetism be weighed?
experiment "How can magnetism be weighed?"
The students analyze the magnetic material properties of aluminum and graphite and compare the diamagnetic and paramagnetic forces quantitatively.
-
8 - How is a magnet formed? What makes it lose its effect?
experiment "How is a magnet formed? What makes it lose its effect?"
According to the station card, the students magnetize a nail using a small bar magnet and demagnetize it by shaking and heating it.
-
9 - The microscopic compass needle model
experiment "The microscopic compass needle model"
The station copies the experimental procedure from Station 8, replacing the nail to be painted over with the model of microscopic compass needles. In this way, the students should be able to understand the microscopic effect of the macroscopic activity of magnetizing and demagnetizing.
-
10 - What happens when a magnet is cut apart?
experiment "What happens when a magnet is cut apart?"
The students examine the magnetic properties of partial magnets using an iron wire that can be broken into individual parts.
-
11 - What shape is a magnetic field?
experiment "What shape is a magnetic field?"
The magnetic field of a long bar magnet is studied using iron filings.
-
12 - How is it possible to block a magnetic field?
experiment "How is it possible to block a magnetic field?"
The students examine which materials can be used to shield a magnetic field.
-
13 - The magnetic field of the Earth
experiment "The magnetic field of the Earth"
The students first deal with the earth and the four cardinal points in the workbook and then build a swimming compass.
-
14 - The history of magnetism
experiment "The history of magnetism"
In order to practice dealing with coordinates, a timeline on the history of magnetism is made in the check booklet at this station.
