No. Look at the MRI, which generates enormous magnetic fields. It does not hurt the body. Even if you look at the iron in the blood, that iron is not ferromagnetic because it is distributed extremely finely, and iron needs to be in bulk form to be ferromagnetic.
Another Answer:
Sometimes. Large rapidly oscillating magnetic fields can cause extensive bodily damage. This damage is exactly similar to electromagnetic radiation damage received by exposure to gamma, x, and ultra violet radiation. Simply put magnetic fields by themselves are relatively harmless, but when used to induce electrical currents or chemical reactions, they can be moderately dangerous.
As with practically everything, magnetic fields do have the potential to harm the human body, but it depends on the degree.
Consider the extreme example: All materials have the property known as diamagnetism, which is basically caused by atoms creating a repulsive magnetic field to oppose an external magnetic field. Given a strong enough external magnetic field, this effect could rip apart the atoms in the body. This situation is unrealistic, but an example of a harmful effect nonetheless.
As far as reality is concerned, there is an ongoing debate about whether magnetic fields can be harmful. There is evidence, but it's hardly conclusive. To learn all about the claims, evidence, studies, and conclusions, see the related link below.

Very intense magnetic fields alter the course of electrical charges, which may have unintended consequences, such as running current through a human body.

yes, it will, from my book.
A magnetometer detects magnetic fields.
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
Yes, several chemical reactions are affected by magnetic or electric fields.
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
They are areas where a magnetic force or pull is felt by an object or body which enters the area.
yes, it will, from my book.
The Magnetic Fields was created in 1989.
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
magnetic fields are essential to production of electricity
Paper is not affected by magnetic fields.
MRI (magnetic resonance imaging) or as it used to be called NMR (nuclear magnetic resonance) has nothing to do with nuclear energy or nuclear radiation. but yes it is nuclear, it has to do with nuclear magnetism. A strong magnet lines up the magnetic fields of the nuclei in the atoms of your body then a radio pulse flips those magnetic fields and by measuring how long the magnetic fields of nuclei in various parts of your body gyrate and take to settle back in alignment with the external field they can compute a picture.

Magnetic Fields - album - was created in 1981-05.
A magnetometer detects magnetic fields.
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
