What is a hill formed by?
well a hill can be formed by a magnetic feild, water,wind, or ice.
The alignment of iron minerals in rocks when they are formed reflects the fact that Earth's has reversed itself several times in the past?
magnetic field.
If a conductor carrying an alternating current is formed into a coil the magnetic field that is generated?
If the current is alternating, the magnetic field will also be alternating.
What has occurred when rocks formed millions of years ago show the location of the magnetic poles at the time of their formation?
Magnetism is a property of certain materials, usually metals, that have an electric dipole on the molecular scale. A dipole is a significant separation between the positive and negative charges in the molecule. Since electrons and protons have spin, and moving electrical charges generate megnetic fields, the dipole generates a net magnetic field. If enough dipoles are oriented in the same direction the body has a net magnetic field. The dipoles can align when sitting in a permanent magnetic field for a long period of time, like underground in the earth's magnetic field.
What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Are conductors magnetic?
While not intrinsically magnetic necessarily, conducting current means a magnetic field is formed.
A permanent emulsion can be formed by?
homogenization
What does the magnetic dip preserved in a rock indicate?
the rock's magnetic latitude at the time that it formed
How is a electro magnet different from a regular bar magnet?
Br magnets and other permanent magnets is formed out of material that creates a and sustains its own magnetic field that is always in effect. These permanent magnetic fields are due to complex interactions of the electrons of the object and the way in which they spin. They are usually made out of paramagnetic materials which have unpaired electron spins in certain orbitals. In the case of permanent magnets, these unpaired spins align to create a ferromagnetic material which exhibits typical magnetic properties. Electromagnets on the other hand require manipulation of moving electrons in electrical current as opposed to in an atom. According to Biot-Savart whenever there is an electric field, a perpendicular magnetic field is generated. Normally, the magnetic field is weak in comparison, but by aligning the electric field in special ways you can amplify the magnetic field, and you can also increase the magnetic field by applying an even stronger current.
Are diamonds magnetic?
no, diamonds are not magnetic as they are made from carbon which is not magnetic either.
What is a hill formed by?
well a hill can be formed by a magnetic feild, water,wind, or ice.
A device formed from an iron core wrapped in current-carrying wire is?
That can be a 'solenoid' or an 'electromagnet'.
What is formed around both magnets in a motor?
A magnetic field.
Regions of the sea floor with negative magnetic anomalies were formed during times when Earth's magnetic field was or had?
reverse polierty
The alignment of iron minerals in rocks when they are formed reflects the fact that Earth's has reversed itself several times in the past?
magnetic field.
What is the term for the distinctive poles formed poles formed when magnetic materials atoms group together in regions?
domains
