1. Applying an external magnetic field gradient allows exerting a force on the nanoparticles. 2. This creates a high field gradient around the smaller, positively charged electrode. 3. The gravitational field gradient is given by the divergence of the gravitational field. 4. Unlike T 2, T 2 * is influenced by magnetic field gradient irregularities. 5. Examples of inhomogeneous effects include a magnetic field gradient and a distribution of chemical shifts. 6. Various strategies are used, from guard rings to overlaps of metallization to spread out the field gradient . 7. Some authors suggest that these abilities may be explained by postulating human sensitivity to small magnetic field gradient changes. 8. Particles suspended in a liquid will be susceptible to the electrical field gradient , this is known as dielectrophoresis. 9. Due to dipole interaction with the electric field gradient the particles are attracted to the gap between the electrodes. 10. The first derivatives of the field, or the second derivatives of the potential, is the electric field gradient .
