121. Small files that demand multiple-key handling are usually stored on magnetic tape and processed sequentially.

122. The magnetic field is thus one aspect of the earth that scientists have studied in detail for centuries.

123. That's ... that's because chromosomes are affected by electric and magnetic fields.

124. They say that the concentrated magnetic fields in sunspots spread out all over the sun somewhat after the maximum of solar activity.

125. Spacecraft electronics systems are vulnerable to damage by high-energy charged particles and are at particular risk during magnetic storms.

126. Two people standing at distant points on the globe would have completely different ideas about where the magnetic north pole lay.

127. Turns on to headings will be made at the standard rate, but using the stop-watch, not magnetic compass.

128. This latter case will favour the use of a sequential magnetic tape file.

129. Occasionally users still require their data on magnetic tape and so this facility remains available.

130. Others use magnetic resonance imaging, like those used to find tissue damage in humans, to detect explosives.

131. Remember that the magnetic compass, clock and stop-watch are your most important navigation instruments.

132. Until recently geophysicists thought that at this low point the magnetic field would also go haywire.

133. Because of its superior contrast capabilities magnetic resonance imaging is the current first choice technique for assessing instability of the cervical spine.

134. Electronic cameras record light as a series of digital impulses on a magnetic disk.

135. This may explain some of the magnetic variations that mystified old-time sailors.

136. A strong magnetic field made the electrons swirl around and so shed energy in the form of radio waves.

137. He felt as if he were pressing against a strong,[http://sentencedict.com/magnetic.html] polarised magnetic force.

138. They compared these numbers to precisely determine muon's magnetic moment.

139. Magnetic ink a magnetized ink that can be read both by humans and by electronic machines.

140. It isn't nuclear radiation but electro magnetic and magnetic fields that are causing the worry.

141. However, the weaker the magnetic field, the lower the frequency needed for a given ion mass.

142. But several areas, notably nuclear magnetic resonance, are less satisfactory.

143. Neutral atoms enter this cloud rather than Io's torus because they are not influenced by magnetic forces whereas charged particles are.

144. Induced-polarisation and resistivity measurements were made in the boreholes, and magnetic susceptibility logs were compiled from data recorded from core.

145. High-speed trains operating on magnetic levitation exist in experimental form only.

146. The magnetic bipolar nature of the features is now firmly established.

147. Tell me, does the magnetic virtue of the needles of the compasses of all those ships attract them thither?

148. The trick is to pack as much magnetic punch into as small an amount of seawater as possible.

149. This unusual complication is best imaged by computed tomography or nuclear magnetic resonance and needs conservative treatment.

150. New media offer many advantages over the magnetic tapes that they replace.
