Science Education Supplies By Eisco

• VISUAL RESULTS || The Magnet Probe is designed to show the three-dimensional nature of a magnetic field easily and conveniently. It illustrates the true shape of a magnetic field far better than either a plotting compass or iron fillings and can be used for individual laboratory or field work or for small scale laboratory demonstrations.
• THREE DIMENSIONAL || The bar magnet rotates freely in x-axis, y-axis, and z-axis (3 dimensions)
• PRODUCT DIMENSIONS || Total Length of the magnet probe is 4.75 inches. Diameter of larger stationary circle: 1.75 inches
• EASY TO USE || Bar magnet painted blue on one pole and red on the other poleThe Magnet Probe can be held in any desired position or orientation in the magnetic field being investigated. The field is indicated by the small magnet, its north pole coloured red, to show the direction of the field.
• EFFICIENT DESIGN || The Magnet Probe consists of a small bar magnet suspended in a gimbal mounting. The supporting frame, handle and bearing pivots are all constructed to avoid any possible magnetic effects on the probe.

• WHITE SANDSTONE | White Sandstone is a recognizable sedimentary rock made up of well sorted and rounded grains of quartz, indicating that the clasts in the rocks have traveled a long distance from their source and experienced heavy erosion along the way
• GREAT FOR GEOLOGY CLASSROOMS | Perfect for lessons in identification and classification of sedimentary rocks
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• BASALT | Basalt makes up a large majority of the earth's oceanic crust. Formed quickly from a magma that is rich in iron, basalt exhibits a dark color and small crystal size
• GREAT FOR GEOLOGY CLASSROOMS | The perfect example of an aphanitic igneous rock. Useful for lessons in igneous rock classification and identification
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• CONGLOMERATE | The large clasts in conglomerate indicate that the pieces of rock underwent a large amount of rolling, bouncing, and other weathering to become round. This implies deposition in a river far from the source of the clasts
• GREAT FOR GEOLOGY CLASSROOMS | Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
